Fix lib/msun/tests/csqrt_test on platforms with 128-bit long double

If long double has more than 64 mantissa bits, using uint64_t to hold the
mantissa bits will truncate the value and result in test failures. To fix
this problem use __uint128_t since all platforms that have
__LDBL_MANT_DIG__ > 64 also have compiler support for 128-bit integers.

Fix warnings in lib/msun/tests/... to help pave way for WARNS?= 6.

- Staticize variables.
- Use nitems liberally. Wherever nitems is used, use unsigned integers
- Remove unused variables (argc, argv, etc)

This fixes most issues -- some issues remain in logarithm_test though.

Integrate a number of testcases from tools/regression/lib/msun

There's no functional change with these testcases; they're purposely

There's no functional change with these testcases; they're purposely
being left in TAP format for the time being

Other testcases which crash on amd64/i386 as-is have not been
integrated yet (they need to be retested on a later version of
CURRENT, as I haven't used i386 in some time)
