[PATCH] D30661: [x86] Split MXCSR into two pseudo-registers

[Andy Kaylor via Phabricator via llvm-commits]

OK, so maybe that puts me back in the position of needing to find a way to conditionally add the MXCSR use/def information only when the strict semantics are required, in which case there would be no significant advantage to splitting the register as I'm proposing here.
