This patch is minimum intrinsics support for VSETVL PASS to support AVL model.

This is the finished version of the last patch I posted before the end
of stage 1. This is quite late for stage 1 (!) and adds new symbols to
the shared library, but I'm pushing it now as it's an important piece of
C++20 support. As noted in the commit message, the symbols being added
are stable
These should really have tests for the new types, but I've been using
them heavily for a few weeks and they work well. I would rather get them
committed now and add tests later.

This patch enhances x86's STV pass to handle VEC_SELECT during general
scalar chain conversion, performing SImode scalar extraction from V4SI
and DImode scalar extraction from V2DI vector registers.
The motivating test case from bugzilla is:
typedef unsigned int v4si
With many thanks to H.J. for doing all the hard work, this patch resolves
two P1 regressions; PR target/106933 and PR target/106959.
Although superficially similar, the i386 backend's two scalar-to-vector
(STV) passes perform their transformations in importantly different ways.
The original pass

This patch is essentially the same as the one used for the 'D' driver and has
been in local use for some time.
Dear all,
the attached patch adds a check for statement function bodies for
invalid uses of dummy arguments. This fixes an ICE-on invalid.
Regtested on x86_64-pc-linux-gnu. OK for mainline?

There's no explicit mention of what GCC compiler supports C++11
and the cross compiler build requirement mentions GCC 4.8 but not
GCC 4.8.3 which is the earliest known version to not run into
C++11 implementation bugs. The following adds explicit wording.
OK for trunk?
Thanks,

This adds a missing effective target check for the permute
recurrence vectorization requires.

When vectorizing SLP loads with permutations we can access excess
elements when the load vector type is bigger than the group size
and the vectorization factor covers less groups than necessary
to fill it. Since we know the code will only access up to
group_size * VF elements in the unpermuted

This script is a helper used to generate dg-output lines from an existing
program output conveniently. It takes care of escaping Tcl and ARE stuff.

This change was almost entirely mechanical. Save for two files which had very
short matches, these changes were produced by two seds and a Perl script, for
the more involved cases. The latter will be added in a subsequent commit. The
former are as follows:
sed -E -i "/dg-output/s/default

Make the output more readable. Don't output anything unless verbose
termination is enabled at configure-time.

Hi!
On the following testcase, we warn with -Wunused-value twice, once
in the FEs and later on cgraphunit again with slightly different
wording.
The following patch fixes that by registering a warning suppression in the
FEs when we warn and not warning in cgraphunit anymore if that happened.
Hi!
The following place in value_replacement is after proving that
x == cst1 ? cst2 : x
phi result is only used in a comparison with constant which doesn't
care if it compares cst1 or cst2 and replaces it with x.
The testcase is miscompiled because we have after the replacement
incorrect range
Hi!
The following testcase ICEs on aarch64, because insert_const_anchor
inserts invalid CONST_INT into the CSE tables - 0x8000 for SImode.
The second hunk of the patch fixes that, the first one is to avoid
triggering undefined behavior at compile time during compute_const_anchors
