Extended Description

vec_cast.ll has 2 actions below.

; RUN: llc < %s -march=x86-64 -mcpu=core2
; RUN: llc < %s -march=x86-64 -mcpu=core2 -disable-mmx

llc barfs on mingw(and maybe msvc) or with -mtriple=x86_64-(mingw32|win32).
I guess this test might pass also for win64.

On CentOS5(x86-64)

Nadav fixed in r126424 and I have fixed a test in r127060.
