so before converting a HOST_WIDE_INT bit offset to unsigned byte offset
we need to punt for too large offsets.  Some places do that, e.g.
isra_get_ref_base_and_offset has
  if (offset < 0 || (offset / BITS_PER_UNIT) > UINT_MAX)
    return false;
but ipa_agg_value_from_jfunc doesn't.

Daily bump.

analyzer: don't warn for deref-before-check for checks in macros [PR108745]

Integration testing shows this patch fixes all 9 known false positives
from -Wanalyzer-deref-before-check within ImageMagick-7.1.0-57, and
eliminates 34 further as-yet unassessed such diagnostics, without
eliminating the 1 known true positive.

This improves the rate of true positives for the warning from
1.56% to 4.76% of the total:

-Wanalyzer-deref-before-check: 1.56% -> 4.76% (GOOD: 1 BAD: 63->20)

RA: Use caller save equivalent memory only for LRA

Recently I submitted a patch to reuse memory with constant address for
caller saves optimization for constant or pure function call.  It
seems to work only for targets using LRA instead of the old reload
pass.  So the patch switches off this optimization when the old reload
pass is used.

gcc/ChangeLog:

* ira.cc (update_equiv_regs): Set up ira_reg_equiv for
valid_combine only when ira_use_lra_p is true.

RA: Use simple LRA for huge functions

The PR108500 test contains a huge function and RA spends a lot of time
to compile the test with -O0.  The patch decreases compilation time
considerably for huge functions.  Compilation time for the PR test
decreases from 1235s to 709s on Intel i7-13600K.

gcc/ChangeLog:

* params.opt (ira-simple-lra-insn-threshold): Add new param.
* ira.cc (ira): Use the param to switch on simple LRA.
