Fix assert about using an undefined physical register in machine instruction verify pass. The reason is that register flag undef is missing when doing transformation from If Conversion Pass. ``` Bad machine code: Using an undefined physical register - function: func_65 - basic block: %bb.0 entry (0x10024740738) - instruction: BCLR killed $cr5lt, implicit $lr8, implicit $rm, implicit undef $x3 - operand 0: killed $cr5lt LLVM ERROR: Found 1 machine code errors. ``` There are also other existing testcases with same issue. So I add -verify-machineinstrs option to open verifying. Differential Revision: https://reviews.llvm.org/D55408 llvm-svn: 348566
