c9c6da61ac Accept 'inreg' attribute on x86 functions as 
meaning sse_regparm (i.e. float/double values go
in XMM0 instead of ST0).  Update documentation
to reflect reality.

743922ea75 Fold immediates into X86 shifts with fast isel. This generates: 
sarl    $3, %ecx

instead of:

movl    $3, %ecx
sarl    %cl, %edx
