Asiri Rathnayake 4cc78d7008 Fix exception address alignment test for EHABI 
This test fails on ARM bare-metal targets because it assumes the Itanium ABI,
whereas EHABI requires the exception address to be 8-byte aligned.

I was a bit puzzled at first because this should've failed on the public
arm-linux builder too. I think the reason it passes there is because we don't
include libunwind headers in the include path when running the libcxxabi tests,
so the system unwind.h gets picked up.

Eric Fiselier c74a2e1297 [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.
