08cf777f9e Really fix AVX tests 
There is no problem with strcmp, it doesn't use the YMM registers.
The math routines might since gcc perhaps generates such code.
Introduce bit_YMM_USBALE and use it in the math routines.

a5b81e1fb7 Remove code without too much effects 
Some of the AVX-specific code is not giving enough speed-up to
justify the extra code.

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.

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.

cf00cc00bc Add ceil implementation for 64-bit machines. 
On 64-bit machines we should not split doubles into two 32 bit
integer and handle the words separately.  We have wide registers.
This patch implements a 64-bit ceil version.  Ideally all other
functions will be converted over time.
