This adds ISel support for lifetime markers in opt levels above O0. It also updates the arm64-irtranslator test, and updates some AArch64 tests that use them for added coverage. It also adds a testcase taken from the X86 codegen tests which verified a bug caused by lifetime markers + stack colouring in the past. This is intended to make sure that GISel doesn't re-introduce the bug. (This is basically a straight copy from what SelectionDAG does in SelectionDAGBuilder.cpp) https://reviews.llvm.org/D57187 llvm-svn: 352410
