Mitch Phillips 592aa29380 [cfi-verify] Validate there are no register clobbers between CFI-check and instruction execution. 
Summary:
This patch adds another failure mode for `validateCFIProtection(..)`, wherein any register that affects the indirect control flow instruction is clobbered to between the CFI-check and the instruction's execution.

Also includes a modification to make MCInstrDesc::hasDefOfPhysReg public.
