31d3cc00b0 Cleanup FMA4 patch
Move the FMA4 code into its own section.  Avoid some of the duplication
of data resulting from the double use of source files.

202c9deb15 Better DLA_FMS
It's better to use __builtin_fma if it works.  Use it for gcc 4.6 and
higher.  Move the x86-64 dla.h to the correct place.

774a2669af Clean up FMA use
The macro's name should reflect that subtraction is being done.  And
use __builtin_fma, it seems to work after all.

ed22dcf691 Provide internal optimizations on x86-64 with SSE4.1
Provide macros so that the internal users can, if possible, directly use
the new instructions.

Also fix up the mathinline.h header when compiling with SSE4.1 enabled.
