7c95495ead avx2 memset: add missing vzeroupper. 
Also improve a few labels. This actually improves performance slightly,
and removes the weird behavior I was seeing around 512 bytes in the
"before" numbers...

15c22cdee0 No tombstones under normal bionic unit tests run. 
Change a test to use a signal that does not trigger a tombstone.

Also changed the gwp_asan_integration.DISABLED_assert_gwp_asan_enabled
test to inherit from the SilentDeathTest to prevent tombstones
being generated.

Test: Ran tests and no tombstones generated.

fe13041d22 Fix potential flakiness in android_mallopt test. 
The set_allocation_limit_multiple_threads test could fail every
once in a while. So rewrite slightly so that the tests wait until
all of the threads are running before letting them start.

I also refactored the code to use std::thread instead of the raw
pthread functions.

Bug: 291672185

Test: Ran the test thousdands of times.

09d3b5065d Disable uchar.start_state test for musl. 
These all appear to be either musl bugs or underspecified corners of
the C standard, so rather than verify the musl behavior I've just
disabled the body of the test for musl.

Now that this is skipped, all the uchar tests are passing for bionic,
glibc, and musl.

c204334b06 Reuse the libm scalbn() as ldexp(). 
These are the same function for machines with binary floats (that is:
all machines), but ldexp() is in libc rather than libm, so we can't just
use an alias.

We were using this duplicate copy of the code, but upstream FreeBSD has
removed it, and I'd prefer to do the same.

Longer term, we should just move all of libm into libc (but keep an
empty libm for compatibility), but this is probably easier for now.

a0d0e350a5 Add missing setlocale calls in tests. 
Doesn't do anything for bionic (which is why this has gone unnoticed),
but it does change the locale for glibc and musl. After this patch,
all these tests pass on glibc. musl is still failing in
uchar.start_state, which I haven't finished investigating.

This should probably be a test fixture so it's harder to forget, but
there are a handful of tests here which don't call setlocale until
part way through the tests, and I'm not certain if that was attempting
to test some non-obvious behavior, or if that was just an accident. I
don't want to change that test behavior before understanding it
better, so this will do for now.

Bug: None
Test: ./tests/run-on-host.sh 64 --gtest_filter="uchar.*"
Test: ./tests/run-on-host.sh glibc --gtest_filter="uchar.*"
Test: ./tests/run-on-host.sh musl --gtest_filter="uchar.*"
