    • [SFN] adjust RTL insn-walking API · f40dd646 
      This patch removes unused RTL functions, introduces alternate ones for
use in a later SFN patch, and regroups other related functions so that
they appear in a more consistent order.

    • Expensive selftests: torture testing for fix-it boundary conditions (PR c/82050) · 421b29d6 
      This patch adds selftest coverage for the fix for PR c/82050.

The selftest iterates over various "interesting" column and line-width
values to try to shake out bugs in the fix-it printing routines, a kind
of "torture" selftest.

Unfortunately this selftest is noticably slower than the other selftests;
adding it to diagnostic-show-locus.c led to:
  -fself-test: 40218 pass(es) in 0.172000 seconds
slowing down to:
  -fself-test: 97315 pass(es) in 6.109000 seconds
for an unoptimized build (e.g. when hacking with --disable-bootstrap).

Given that this affects the compile-edit-test cycle of the "gcc"
subdirectory, this felt like an unacceptable amount of overhead to add.

I attempted to optimize the test by reducing the amount of coverage, but
the test seems useful, and there seems to be a valid role for "torture"
selftests.

Hence this patch adds a:
  gcc.dg/plugin/expensive_selftests_plugin.c
with the responsibility for running "expensive" selftests, and adds the
expensive test there.  The patch moves a small amount of code from
selftest::run_tests into a helper class so that the plugin can print
a useful summary line (to reassure us that the tests are actually being
run).

With that, the compile-edit-test cycle of the "gcc" subdir is unaffected;
the plugin takes:
  expensive_selftests_plugin: 26641 pass(es) in 3.127000 seconds
which seems reasonable within the much longer time taken by "make check"
(I optimized some of the overhead away, hence the reduction from 6 seconds
above down to 3 seconds).

    • [PR80693] drop value of parallel SETs dropped by combine · b92977ee 
      When combine drops a REG_UNUSED SET in a parallel, we have to clear
cached values, so that, even if the REGs remain used (e.g. because
they were referenced in the used SET_SRC), we will not use properties
of the dropped modified value as if they applied to the preserved
original one.

We fail to adjust REG_N_SETS.
