Start using GPR's to copy around mmx value instead of mmx regs. GCC apparently does this, and code depends on not having to do emms when this happens. This is x86-64 only so far, second half should handle x86-32. rdar://5741668 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47470 91177308-0d34-0410-b5e6-96231b3b80d8

; This test should use GPRs to copy the mmx value, not MMX regs. Using mmx regs,

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786.
