Description of problem:
Currently EC xlator uses inline assembler and makes use of XMM registers of Intel's SSE2 extensions.
This is not portable and should be converted to standard C.
Version-Release number of selected component (if applicable): 3.6

ec: Removed SSE2 dependency
This patch implements the Galois Field multiplications using pure C
code without any assembler support. This makes the ec xlator portable
to other architectures.
In the future it will be possible to use an optimized implementation
of the multiplications using architecture dependent facilities (it
will be automatically detected and configured). To allow bricks with
different machine word sizes to be able to work seamlessly in the
same volume, the minimum fragment length to be stored in any brick
has been fixed to 512 bytes. Otherwise, different implementations
will corrupt the data (SSE2 used 128 bytes, while new implementation
would have used 64).
This patch also removes the '-msse2' option added on patch
