compiler: revert `for package-scope "a = b; b = x" just set "a = x"`
This patch to the Go frontend reverts https://go.dev/cl/245098, which
introduced incorrect initialization ordering. This patch adjusts the
runtime package to work even with that change reverted.

Can someone, anyone, please commit the attach patch, which is
also attached to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89125
where one can read the audit trail. The original patch was
submitted 2 years ago, and required manual intervention due to
the recent *.c to *.cc rename.

Hi!
The CONSTRUCTOR_PLACEHOLDER_BOUNDARY bit is supposed to separate
PLACEHOLDER_EXPRs that should be replaced by one object or subobjects of it
(variable, TARGET_EXPR slot, ...) from other PLACEHOLDER_EXPRs that should
be replaced by different objects or subobjects.
The bit is set when finding PL

Sorry, I should have realised this at the time, but I don't think

The error message changes from "needs isa option -mcrc32" to "target
specific option mismatch" with the #pragma change.

Hi,
As PR105271 shows, __builtin_altivec_neg_v2di requires option
-mpower8-vector as its pattern expansion relies on subv2di which
has guard VECTOR_UNIT_P8_VECTOR_P (V2DImode). This fix is to move
the related lines for __builtin_altivec_neg_v2di to the section
of stanza power8-vector.

TOPN metrics are histograms that contain overall count and per-bucket
count. Overall count can be nevative when two profiles merge and some
of per-bucket metrics are dropped.
Noticed as an ICE on python PGO build where gcc crashes as:
