Fix incorrectly aligned exceptions in 32 bit builds.
This patch fixes a bug where exceptions in 32 bit builds
would be incorrectly aligned because malloc only provides 8 byte aligned
memory where 16 byte alignment is needed.
This patch makes libc++abi correctly use posix_memalign when it's
available. This requires defining _LIBCPP_BUILDING_LIBRARY so that
libc++ only defines _LIBCPP_HAS_NO_ALIGNED_ALLOCATION when libc doesn't
support it and not when aligned new/delete are disable for other
reasons.
This bug somehow made it into the 7.0 release, making it a regression.
Therefore this patch should be included in the next dot release.

Fully Reformat fallback_malloc.cpp
This patch fully reformats fallback_malloc.cpp. Previously the test
was a mess of different styles and indentations. This made it very
hard to work in and read. Therefore I felt it was best to re-format
the whole thing.
Unfortuantly this means some history will be lost, but hopefully
much of it will still be accessible after ignoring whitespace changes.

[libcxxabi] Fix alignment of allocated exceptions in 32 bit builds
Summary:
In 32 bit builds on a 64 bit system `std::malloc` does not return correctly aligned memory. This leads to undefined behavior.
This patch switches to using `posix_memalign` to allocate correctly aligned memory instead.

[libc++abi] Clean up visibility
Use the libc++abi visibility macros instead of pragmas or using
visibility attributes directly. Clean up redundant attributes on
definitions (where the declarations already have visibility attributes
applied, from either libc++ or libc++abi headers).
Introduce _LIBCXXABI_WEAK as a drive-by cleanup, which matches the
semantics of _LIBCPP_WEAK.
No functional change. Tested by building on Linux before and after this
change and verifying that the list of exported symbols is identical.

[libcxxabi] Refactor pthread usage into a separate API
This patch refactors all pthread uses of libc++abi into a separate API. This
is the first step towards supporting an externlly-threaded libc++abi library.
I've followed the conventions already used in the libc++ library for the same
purpose.

Recommit r282692: [libc++abi] Use fallback_malloc to allocate __cxa_eh_globals in case of dynamic memory exhaustion.
Throwing an exception for the first time may lead to call calloc to
allocate memory for __cxa_eh_globals. If the memory pool is exhausted
at that moment, it results in abnormal termination of the program.
This patch addresses the issue by using fallback_malloc in that case.
In this revision, some restrictions were added into the test to not
run it in unsuitable environments.
