Add benchmark support for frexp, frexpf, and frexpl to measure the
performance improvement of the fast path optimization.
- Created frexp-inputs, frexpf-inputs, frexpl-inputs with random test values
- Added frexp, frexpf, frexpl to bench-math list
- Added CFLAGS to disable builtins for accurate benchmarking
These benchmarks will be used to quantify the performance gains from the
fast path optimization for normal floating-point numbers.
