This new matcher does not use death tests to check if SIGFPE is raised.
Instead, that a SIGFPE was raised is checked using a SIGFPE signal handler.

Redefined FPBits.h and LongDoubleBitsX86 so its implementation works for the Windows
and Linux platform while maintaining a packed memory alignment of the precision floating
point numbers. For its size in memory to be the same as the data type of the float point number.
This change was necessary because the previous attribute((packed)) specification in the struct was not working
for Windows like it was for Linux and consequently static_asserts in the FPBits.h file were failing.

This helps us avoid the uncomfortable reinterpret-casts. Avoiding the
reinterpret casts prevents us from tripping the sanitizers as well.

This eliminates UnitTest's dependency on FPUtil and hence prevents
non-math tests from depending indirectly on FPUtil. The patch
essentially moves some of the existing pieces into a library of its own.
Along the way, renamed add_math_unittest to add_fp_unittest.
