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.

The new code added is still very x86_64 specific. AArch64 support will
be added very soon and refactoring of the loader code will be done as
part of the patches adding it.

Current implementations of single precision and double precision
floating point operations operate on bits of the integer type of
same size. The code made use of magic masks which were listed as
literal integer values. This is not possible in the case of long
double type as the mantissa of quad-precision long double type used
on non-x86 architectures is wider that the widest integer type for
which we can list literal values. So, in this patch, to avoid
using magic masks specified with literal values, we use packed
bit-field struct types and let the compiler generate the masks.
This new scheme allows us to implement long double flavors of the
various floating point operations. To keep the size of the patch
small, only the implementations of fabs and trunc have been
switched to the new scheme. In following patches, all exisiting
implementations will be switched to the new scheme.

The current tests verify if the result of -infinity is a quiet NaN with
sign bit set. But, that need not be the case on all platforms. So, just
checking that the result is a quiet NaN and ignoring the sign bit is
good enough.
Conditionally adding subdirectories was missed in a few places previously.
This change adds the conditionals. A sub-directory was being added
needlessly in another place. That has been removed.
Summary:
If a test depends on a skipped entrypoint, then the test is also
skipped. This setup will be useful as we gradually add support for
more operating systems and target architectures.

Summary:
This is failing on the asan build because we use `-nostdlib`.
I also took this opportunity to make the target name match the naming structure we've been using.

Summary:
This patch aims to add integration tests to check the following:
1) Header files are generated as expected.
2) Libc functions have the correct public name.
3) Libc functions have the correct return type and parameter types.
4) Symbols are exposed in the public lib.a files.
