The Msan unit tests are still broken and by this point, I think we
should start over.

Alexander Potapenko f06fbd4794 [msan] Remove a failing test from MemorySanitizer.ICmpRelational 
This is a follow-up to r302787, which broke MemorySanitizer.ICmpRelational.

MSan is now reporting a false positive on the following test case:
  TestForNotPoisoned((poisoned(-1, 0x80000000U) >= poisoned(-1, 0U)))
, which is sort of anticipated, because we're approximating the comparison
with an OR of the arguments' shadow values.

Adhemerval Zanella 6b989288ab [msan] Fix getmntent{_r} for empty /etc/fstab 
Some configuration (for instance default docker ubuntu images) uses
a default empty and invalid /etc/fstab configuration file.  It makes
any call to getmntent return NULL and it leads to failures on
Msan-aarch64{-with-call}-Test/MemorySanitizer.getmntent{_r}.

This patch fixes it by creating a temporary file with some valid
entries (although not valid for the system) to use along with
setmntent/getmntent.

Evgeniy Stepanov 32773333cb [msan] Implement GetPageSize in the test. 
Instead of calling a sanitizer_common function, implement GetPageSize in the
test directly. MSan runtime does not export __sanitizer::* symbols, and the
current code breaks when the test and the runtime library are in the separate
link units (ex. when the test is built as a shared library).

Marcin Koscielnicki c5d2ff8099 [msan] Don't hardcode 4kiB page size in msan_test.cc. 
This breaks the valloc test on PowerPC, which has 64kiB pages.  Since
getting page size portably is nontrivial, and there's already a function
for that in __sanitizer, just use it.  Unfortunately, sanitizer_common.h
conflicts with the interface headers inclucded by msan_test.cc (and a few
of its own macros), so we have to declare it manually.

Adhemerval Zanella 29ffb68259 [compiler-rt] [msan] Couple of fixes for msan with libc++ 
This patch adds some fixes for MSAN with libc++ for aarch64:

1. Adds the libmsan_loadable name for aarch64.
2. Fixes some pthread_attr_setstacksize for aarch64, since glibc sets
   the mininum stack size to be higher than the x86_64 default (16KB
   vs 128KB).
3. Fixes a swprintf null char constant definition.
