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.

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.
