Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down · d60fa58b

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

Unfortunately several files in MC are badly violating layering rule by using · c7ac690b

Evan Cheng authored Jul 14, 2011

TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are
other cases of violations, but this is probably the worst.

This patch is but one small step towards fixing this. 500 more steps to go. :-(
