Calling MarkTypeUsedInInterface before inlining is problematic (when
using the containing function as the reference source), because we end
up attaching a relocation to the original function, which is then
deadcode removed because all instances of it were inlined. (All other
current uses of MarkTypeUsedInInterface happen after inlining, so they
don't have this problem.)
Instead, attach the relocation to the dictionary in which the type
appears. This should always work, because if the dictionary is ever
deadcode eliminated, then the type can never be put in an interface,
which means we indeed don't need its methods.
This CL is a bit overkill, as not *all* types in the dictionary need
this mark, but it is sufficient for now.

This CL makes two changes:
1. It moves object symbols and code tags into a new "relocName"
relocation, which should eventually allow getting rid of objStub.
2. It moves the type parameter data into the relocObjDict relocation,
so everything related to writing out dictionaries is contained there.

CL 330330 moved logic for wrapping go/defer from order to esacpe
analysis. It introduced a bug involves go/defer statement with ABI0
functions.
Consider this following code:
package p
//go:cgo_unsafe_args
func g(*int) (r1 struct{}) {
return
}
func f() {
defer g(new(int))
}
g is a cgo-like generated function with ABI0. While compiling g, we set
the offset per ABI0.
The function f is rewritten into:
func f() {
_0, _1 := g, new(int)
defer func() { _0(_1) }()
}
The temporary _0 hold function value with the same type as g, but with
class PAUTO. Thus ssagen/ssa.go:state.call cannot handle it and use
ABIDefault to set the offset, causes the offset of r1 changed
CL 330332 intended to optimize code generated for wrapping function, by
rewriting the wrapper function into:
func f() {
_0 := new(int)
defer func() { g(_0) }()
}
So it fixed the bug unintentionally.
This CL add regression test for this bug, and also add a comment to
explain while not wrapping declared function is important.

We have almost 200 uses of the "assert" helper functions in noder and
typecheck. Clearly the tiny bit of extra convenience of writing a
one-line assertion rather than an if+panic is helpful, so we might as
well add functions for this to base itself so that it's easier to
write more informative error messages.

For traceback argument printing, we want to print at most 10
words, then print "..." if there are still more args and/or
fields. The current code has off-by-one error that for 11
non-aggregate typed args, it prints the first 10 but without the
"...". Also, for aggregate-typed args, in some cases it may print
an extra "..." when there is actually no more fields.
The problem for this is that visitType return false (meaning not
to continue visiting) if it reaches the limit anywhere during the
recursive visit. It doesn't distinguish whether it has printed
anything for the current arg. If it reaches the limit before it
prints anything, it means that we're visiting the extra arg/field,
so the caller should print "..." and stop. If it prints
something then reaches the limit, however, the caller should keep
going, and only print "..." at the next iteration when there is
actually an extra arg/field. This CL does so.

In CL 326211 a change was made to switch "go.map.zero" symbols from
non-pkg DUPOK symbols to hashed symbols. The intent of this change was
ensure that in cases where there are multiple competing go.map.zero
symbols feeding into a link, the largest map.zero symbol is selected.
The change was buggy, however, and resulted in duplicate symbols in
the final binary (see bug cited below for details). This duplication
was relatively benign for linux/ELF, but causes duplicate definition
errors on Windows.
This patch switches "go.map.zero" symbols back from hashed symbols to
non-pkg DUPOK symbols, and updates the relevant code in the loader to
ensure that we do the right thing when there are multiple competing
DUPOK symbols with different sizes.

because in a function instantiation, any method call on this type arg
will be a generic method call (requiring a dictionary), rather than a
direct method call on the underlying type (no dictionary).
So, we add the instshape prefix to the gcshape name for instantiated
types, and we make it a defined type with that name.
