When the .c/.S file neither uses nor modifies macros defined in
sysdep.h there is no point to #include it. The same goes for
math_ldbl_opt.h except that it includes shlib-compat.h, and if
compat_symbol is redefined we need to include shlib-compat.h first.

This implementation utilizes vectors to improve performance
compared to current byte by byte implementation for POWER7.
The performance improvement is upto 4x. This patch is tested
on powerpc64 and powerpc64le.
