The code was incorrectly counting the number of identical instructions, and therefore tried to predicate an instruction which should not have been predicated. This could have various effects: a compiler crash, an assembler failure, a miscompile, or just generating an extra, unnecessary instruction. Instead of depending on TargetInstrInfo::removeBranch, which only works on analyzable branches, just remove all branch instructions. Fixes https://bugs.llvm.org/show_bug.cgi?id=3D43121 and https://bugs.llvm.org/show_bug.cgi?id=3D41121 . Differential Revision: https://reviews.llvm.org/D67203 This should fix "Unable to predicate BX killed renamable $r0" errors when building the lang/spidermonkey170 and lang/spidermonkey38 ports for armv7 and armv6.
