Test for __cxa_thread_atexit_impl when cross-compiling libstdc++ for GNU targets.
I noticed that when testing glibc with a cross compiler I got
UNSUPPORTED: nptl/tst-thread_local1
because the libstdc++-v3 configuration for cross compiling defaulted
to __cxa_thread_atexit_impl not being available. This patch fixes
GLIBCXX_CROSSCONFIG to run the same test (for the case covering
targets with glibc) for __cxa_thread_atexit_impl as for native
compilation, just as it runs most of the other tests done for native
compilation (for these targets, it's not possible to build libstdc++
without already having built libc, so link tests are OK).

As the PR points out, the "simple" reorder algorithm makes bigger code
than the STC algorithm did, for -Os, for x86. I now tested it for many
different targets and it turns out to be worse everywhere.
This simple patch tunes "simple" a bit; this makes it better than STC
almost everywhere. The only exceptions (for the targets where I have
results) are x86 and mn10300. For those targets it may be best to switch
the default algorithm for -Os to STC.

[PATCH PR target/67366 2/2] [gimple-fold.c] Support movmisalign optabs in gimple-fold.c
This patch by Richard allows for movmisalign optabs to be supported
in gimple-fold.c. This caused a bit of pain in the testsuite with strlenopt-8.c
in conjunction with the ARM support for movmisalign_optabs as the test
was coded up to do different things depending on whether the target
supported misaligned access or not. However now with unaligned access
being allowed for different levels of the architecture in the arm backend,
the concept of the helper function non_strict_align mapping identically
to the definition of STRICT_ALIGNMENT disappears.
Adjusted thusly for ARM. The testsuite/lib changes were tested with an
arm-none-eabi multilib that included architecture variants that did not
support unaligned access and architecture variants that did.
The testing matrix for this patch was:
1. x86_64 bootstrap and regression test - no regressions.
2. armhf bootstrap and regression test - no regressions.
3. arm-none-eabi cross build and regression test for
{-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp}
{-mthumb/-march=armv8-a/-mfpu=crypto-neon-fp-armv8/-mfloat-abi=hard}
{-marm/-mcpu=arm7tdmi/-mfloat-abi=soft}

Make tree_expr_nonnegative_warnv_p recurse into SSA names
The upcoming patch to move sqrt and cbrt simplifications to match.pd
caused a regression because the (abs @0)->@0 simplification didn't
trigger for:
(abs (convert (abs X)))
The simplification is based on tree_expr_nonnegative_p, which at
the moment just gives up if it sees an SSA_NAME.
This patch makes tree_expr_nonnegative_p recurse into SSA name
definitions, but limits the depth of recursion to a small number
for the reason mentioned in the comment (adapted from an existing
comment in gimple_val_nonnegative_real_p). The patch reuses code
in tree-vrp.c, moving it to gimple-fold.c. It also replaces calls
to gimple_val_nonnegative_real_p with calls to tree_expr_nonnegative_p.
A knock-on effect is that we can now prove _i_589 < 0 is false in
sequences like:
i_1917 = ASSERT_EXPR <i_1075, i_1075 == 0>;
_i_589 = (const int) i_1917;
_i_1507 = ASSERT_EXPR <_i_589, _i_589 < 0>;
This defeats an assert in tree-vrp.c that ASSERT_EXPR conditions
are never known to be false. Previously the assert only ever used
local knowledge and so would be limited to cases like x != x for
integer x. Now that we use global knowledge it's possible to prove
the assertion condition is false in blocks that are in practice
unreachable. The patch therefore removes the assert.
Bootstrapped & regression-tested on x86_64-linux-gnu. I didn't write
a specific test because this is already covered by the testsuite if
the follow-on patch is also applied.

gather bbs and conditions in a single walk through dominators
Clean up the function to build scop's basic blocks and the function
that gathers the conditions under which a basic block is executed. We remove
one traversal of the dominator tree.
This refactoring was triggered by the need of a vec<bb> of all the basic blocks
in a region. We will use that vector in a patch that removes the out-of-ssa
translation of scalar dependences: we will iterate through the basic blocks of a
region to record scalar dependences crossing bbs or going out of the region.
The patch passes bootstrap and regtest on x86_64-linux.
