...at least when building against glibc-2.26-16.fc27.x86_64

The test was not passing on targets where allocator_may_return_null
defaults to true. Change the test to a lit test so that we can test both
situations.

Summary:
CheckForPvallocOverflow was introduced with D35818 to detect when pvalloc
would wrap when rounding up to the next multiple of the page size.
Add this check to MSan's pvalloc implementation.
This time I made sure I was actually running (and writing) the correct tests,
and that they are passing...

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

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.

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.

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).

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.

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.
