The assignment operation in the program seems to be redundant, the first judgment will continue to overwrite the previous value.
The subsequent slicing operation will cut all the values without frequency.

`go mod tidy` results in panic due to nil pointer dereference with the
current implementation. Though the panic occurs only in a limited situation
described as below, we had better fix it.
Situation:
- go.mod is in the exactly system's temporary directory (i.e. temp root)
- `go mod tidy` in temp root or in the child directory not having go.mod
No go.mod are found in the situation (i.e. *modFile is nil), however,
*modFile is referred without nil check.
Although just adding nil check works well, the better solution is using
ModFile() function. It works as same as the current implementation and,
in addition, it has either nil check and user friendly error indication.
With using it, users can get a proper error message like "go.mod file not
found in current directory or any parent directory" instead of a panic.

_restgpr0_n: Restore Rn-R31 from R1, and return to saved LR

Add several new functions similar to those suggested by the
PPC64 ELFv2 ABI. And update the linker to scan external relocs
for these calls, and redirect them to runtime.elf_<func>+offset
in runtime/asm_ppc64x.go.
Similarly, code which generates plt stubs is moved into
a dedicated function. This avoids an extra scan of relocs.

Avoid coercing the CR bit into a GPR register type argument, and
move the existing usage to CRx_y register types. And, update the
compiler usage to this. This transformation is done internally,
so it should not alter existing assembly code.
Likewise, add assembly tests for all optab entries of BC/BR. This
found some cases which were not possible to realize with handwritten
asm, or assemble to something very unexpected if generated by the
compiler. The following optab entries are removed, and the cases
simplified or removed:
{as: ABR, a3: C_SCON, a6: C_LR, type_: 18, size: 4}
This existed only to pass the BH hint to JMP (LR) from compiler
generated code. It cannot be matched with asm. Instead, add and
support 4-operand form "BC{,L} $BO, $BI, $BH, (LR)".
{as: ABR, a1: C_REG, a6: C_CTR, type_: 18, size: 4}
Could be used like "BR R1, (CTR)", but always compiles to bctr
irrespective of arg 1. Any usage should be rewritten as "JMP (CTR)",
or rewritten if this was not the intended behavior.
{as: ABR, a6: C_ZOREG, type_: 15, size: 8}:
{as: ABC, a6: C_ZOREG, type_: 15, size: 8},
Not reachable: 0(reg) is coerced to reg in assembler frontend.
{as: ABC, a2: C_REG, a6: C_LR, type_: 18, size: 4}
{as: ABC, a2: C_REG, a6: C_CTR, type_: 18, size: 4}
Only usable from the compiler. However, the compiler does not
generate this form today. Without a BO operand (usually in a1), it
is not clear what this should assemble to.

There is a TODO comment that checking hidden visibility is
probably not the right thing to do. I think it is indeed not. Here
we are not referencing symbols across DSO boundaries, just within
an executable binary. The hidden visibility is for references from
another DSO. So it doesn't actually matter.
This makes cgo internal linking tests work on ARM64 with newer
GCC. It failed and was disabled due to a visibility hidden symbol
in libgcc.a that we didn't handle correctly. Specifically, the
problem is that we didn't mark visibility hidden symbol references
SXREF, which caused the loader to not think it is an unresolved
external symbol, which in turn made it not loading an object file
from the libgcc.a archive which contains the actual definition.
Later stage when we try to resolve the relocation, we couldn't
resolve it. Enable the test as it works now.

There is a change to p256MovCond based on a reviewer's comment.
LXVD2X replaces the use of LXVW4X in one function.
In addition, some refactoring has been done to this file to
reduce size and improve readability:
- Eliminate the use of defines to switch between V and VSX
registers. V regs can be used for instructions some that
previously required VSX.
- Use XXPERMDI instead of VPERM to swap bytes loaded and
stored with LXVD2X and STXVD2X instructions. This eliminates
the need to load the byte swap string into a vector.
- Use VMRGEW and VMRGOW instead of VPERM in the VMULT
macros. This also avoids the need to load byte strings to
swap the high and low values.
These changes reduce the file by about 10% and shows an
improvement of about 2% at runtime.

The goal of this CL is to move the implementation to the new interface
with the least amount of changes possible. A follow-up CL will add
documentation and cleanup the assembly API.
* SetBytes does the element and point validity checks now, which were
previously implemented with big.Int.
* p256BaseMult would return (0:0:1) if the scalar was zero, which is
not a valid encoding of the point at infinity, but would get
flattened into (0,0) by p256PointToAffine. The rest of the code can
cope with any encoding with Z = 0, not just (t²:t³:0) with t != 0.
* CombinedMult was only avoiding the big.Int and affine conversion
overhead, which is now gone when operating entirely on nistec types,
so it can be implemented entirely in the crypto/elliptic wrapper,
and will automatically benefit all NIST curves.
* Scalar multiplication can't operate on arbitrarily sized scalars (it
was using big.Int to reduce them), which is fair enough. Changed the
nistec point interface to let ScalarMult and ScalarBaseMult reject
scalars. The crypto/elliptic wrapper still does the big.Int
reduction as needed.
The ppc64le/s390x assembly is disabled but retained to make review of
the change that will re-enable it easier.
Very small performance changes, which we will more then recoup when
crypto/ecdsa moves to invoking nistec directly.

No longer needed. We now always directly construct TFUNC types when
needed.

This CL reworks DeclFunc so that we no longer need to internally
create an ir.FuncType. The next CL will remove ir.FuncType entirely.

Currently all typecheck.DeclFunc callers already construct a fresh new
ir.FuncType, which is the last type expression kind that we represent
in IR.
This CL pushes all of the ir.FuncType construction down into
typecheck.DeclFunc. The next CL will simplify the internals so that we
can get rid of ir.FuncType altogether.

Ident, ParenExpr, SelectorExpr, and StarExpr used to need to be
allowed as Ntypes for the old -G=0 type checker to represent some type
expressions before type checking, but now they're only ever used to
represent value expressions.

Type arguments are always type expressions, which are semantically
represented by Ntype.
In fact, the slice should probably just be []*types.Type instead, and
that would remove a lot of ir.TypeNode wrapping/unwrapping. But this
lead to issues within the stenciling code, and I can't immediately
make sense why.

It's no longer needed, since type expressions are all evaluated by
types2. We can just use Node.Type instead.

All callers were already using TypeNode to get an Ntype anyway, so
just push the TypeNode constructor down into NewCompLitExpr. Prep
refactoring for next CL to remove the Ntype field.
