combine: Update links correctly for new I2 (PR84169)
If there is a LOG_LINK between two insns, this means those two insns
can be combined, as far as dataflow is concerned. There never should
be a LOG_LINK between two unrelated insns. If there is one, combine
will try to combine the insns without doing all the needed checks if
the earlier destination is used before the later insn, etc.
Unfortunately we do not update the LOG_LINKs correctly in some cases.
This patch fixes at least some of those cases.

those to i2, not i1. Partially rewrite this scan code.

They aren't needed, and could potentially cause unlikely symbol name
collisions. Also, the runtime package's reference to main could cause
the runtime package to define main.main..f, which could also be
defined in the main package if it does something like fmt.Print(main).

Add a DECL_EXPR for VLA pointer casts (PR 84305)
This PR was about a case in which we ended up with a MULT_EXPR
that was shared between an ungimplified VLA type and a pointer
calculation. The SSA names used in the pointer calculation were
later freed, but they were still there in the VLA, and caused an
ICE when remapping the types during inlinling.
The fix is to add a DECL_EXPR that forces the VLA type sizes to be
gimplified too, but the tricky part is deciding where. As the comment
in grokdeclarator says, we can't just add it to the statement list,
since the size might only be conditionally evaluated. It might also
end up being evaluated out of sequence.
The patch gets around that by putting the DECL_EXPR in a BIND_EXPR
and adding the BIND_EXPR to the list of things that need to be
evaluated for the declarator.

compiler: error on func declaration/definition
Long long long ago Go permitted writing
func F()
in one file and writing
func F() {}
in another file. This was removed from the language, and that is now
considered to be a multiple definition error. Gccgo never caught up
to that, and it has been permitting this invalid code for some time.
Stop permitting it, so that we give correct errors. Since we've
supported it for a long time, the compiler uses it in a couple of
cases: it predeclares the hash/equal methods if it decides to create
them while compiling another function, and it predeclares main.main as
a mechanism for getting the right warning if a program uses the wrong
signature for main. For simplicity, keep those existing uses.
This required a few minor changes in libgo which were relying,
unnecessarily, on the current behavior.

DWARF: no location for non-definition DECLs with non-trivial DECL_VALUE_EXPR
This patch restricts the set of cases in which we allow the generation of
location attributes for variables that are not defined in the current unit.
For such variables with complex DECL_VALUE_EXPR trees, generating a location
attribute can end up creating relocations to text symbols in the debug section
of LTO object files, which is not valid.

[LVU] set ppc64 blockage's length to zero
LVU requires the zero-length (pseudo) insns's length to reflect
reality. If they don't, it may assume there's a PC change where there
isn't any, and then a view-aware assembler will detect the problem and
complain about out-of-sync views.
ppc blockage pseudo-insns did not have the length attribute explicitly
set in them, so they inherited the attribute's default value, and that
was nonzero.
