8d13f8f104 Remove non-DebugLoc versions of BuildMI from X86. 
There were some that might even matter in X86FastISel.

bc5cbb8be9 Move the code that inserts X87 FP_REG_KILL instructions from a 
special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.
