fast math optimization patch
...the blow by blow description of the patch:
- Add fast_math.[ch]
- fast_rsqrt_est -- fast reciprocal square root estimate (i.e.,
1.0/sqrt(x))
- fast_sqrt_est -- fast square root estimate
- fast_log_est -- fast natural log estimate
- Adds a IEEE structure for floats
- Adds VORBIS_EXACT_FLOAT_RESULTS. If this is defined, the
estimations are turned off.
- Modify os.h
- Remove _V_IFDEFJAIL_H_. The entire file is already in an _OS_H
ifdef,
so this shouldn't be necessary.
- Added normalized processor ifdef support (VORBIS_X86 and
VORBIS_PPC so far).
