Szabolcs Nagy b99d49e506 New pow implementation 
The new implementation is provided under !__OBSOLETE_MATH, it uses
ISO C99 code.  With default settings the worst case error in nearest
rounding mode is 0.54 ULP with inlined fma and fma contraction.  It uses
a 4 KB lookup table in addition to the table in exp_data.c, on aarch64
.text+.rodata size of libm.a is increased by 2295 bytes.

Improvements on Cortex-A72:
latency: 3.3x
thruput: 4.9x
