The current assembler uses REGTMP as a temporary destination register,
when optimizing one instruction into a multi-instruction sequence. But
in some cases, when the source register is REGTMP, this behavior is
incorrect.
For example:
ADD $0x1234567, R27, R3
The current assembler encodes it into
MOVD $17767, R27
MOVK $(291<<16), R27
ADD R27, R27, R3
It is illegal to overwrite R27. This CL adds the related checks.
Add test cases.

In indexed export, values are always exported along with their type
and are encoded in a type-sensitive manner, because this matches how
cmd/compile handled constants internally.
However, go/types intentionally differs from this, decoupling type
from value representation. As unified IR strives to be more
go/types-centric, it makes sense to embrace this and make values a
more first-class encoding.

This is annoying because it takes a while to notice that

Detect cycles, and when we detect one, print the sequence
of rewrite rules that occur within a single cycle before crashing.

While type checking expressions involving interface types, it is
possible that their type set is used before delayed actions are

To avoid the panics, store a *Checker on Interface for use in between
checking of the interface type expression and processing of delayed

Setup .TOC. to point to the same place for all objects. Today, the linker
assumes all call relocations can use the local function entry point of
imported object files. This requires a consistent pointer across all
objects.
This intentionally computes the .TOC. pointer in all linking configurations.
In some cases the .TOC. is not used today (e.g linking position-dependent go
only code). It is harmless and simple to compute in all cases, so just
do it for easier maintenance.
Notably, .TOC. is used in some cases when static linking is requested on
ppc64le/linux:
* Position-independent C code using a PC-rel relocation against .TOC.. cgo
generated C object files are usually compiled PIC even if the go binary
itself is not.
* Anything which causes PLT stub generation. The stubs always generate
a .TOC. relative relocation.
* The race detector. Today, this links in an externally compiled archive which
contains position-independent object files.
Similarly, position-independent linking is always punted to the external
linker on ppc64 today.

But that setting code is no longer needed, as long as we call
SetRParams() soon after calling NewIncompleteNamedType(), before
creating/translating the underlying type (which we do). The
HasTParam/HasShape attribute can only come from setting of rparams or a
direct typeparam/shape somewhere in the underlying type, both of which
don't depend on recursion, etc. (as long as the rparams are set early).
Added a check that HasTParam/HasShape are set correctly for the cached
pointer/slice elems in NewPtr() and NewSlice().

In CL 345572, we used the reflect.Value.SetLen method to avoid
extra memory allocation for reflect.Value.Slice.

We should be putting a newly instantiated imported type in
Instantiate/doInst onto the instTypeList, so its methods/dictionaries
are instantiated. To do this, we needed a more general way to add a
type to instTypeList, so add NeedInstType(), analogous to
NeedRuntimeType(). This has the extra advantage that now all types
created by the type substituter are added to instTypeList without any
extra code, which was easy to forget. doInst() now correctly calls
NeedInstType().
This is a bit aggressive, since a fully instantiated type in a generic
function/method may never be used, if the generic method is never
instantiated in the local package. But it should be fairly uncommon for
a generic method to mention a fully instantiated type (but it does
happen in this bug).
Fixes both cases mentioned in the bug.
