Martin's recent changes added the return type to the dump file.
Naturally we have tests that count "int" or pointers, which can show up
in the return type.
This patch adjusts the tests to the current output. Pushed to the trunk.

As noted in bug 95630, C11 removed a restriction in C99 on comparing

Commit 229752afe315 ("VEC_COND_EXPR optimizations") has improved code
generation: we no longer need "vx x,x,-1", which turned out to be
superfluous. Instead, we simply swap 0 and -1 arguments of the
preceding "vsel".

The patch below is based on a previous version by Steve.
The present version fixes an additional copy&paste error.
Needless to say that it (still!) regtests cleanly on x86_64-pc-linux-gnu.
OK for master? As it appears safe, OK for backport to at least 10-branch?

So the primary purpose of this patch is to make it easier to write tests
for removal of useless test/compare insns on the H8.
In simplest terms the costing model in the H8 port tends to encourage
changing something like
x = y + 4;
if (x == 0)
into
x = y + 4;
if (y == -4)

Hello,
The current config.guess/sub version do not support the recently released
Darwin platforms; current upstream does.
This imports from:

Date: 2020-11-07 04:46:23 +
ChangeLog:

This makes SLP discovery handle associatable (including mixed

While it works it still is a prototype only. I need to consider

This tweaks the 'included from ...' printing to deal with imports in
the 'include' path. One new thing is that there can now be two
'include' names on a single line. For example 'in module X, included
at Y'. This reads better than placing them on different lines.

It survives testing.
There's the second part which adds -frecord-gcc-switches-format.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
