This adds instruction selection support for lifetime markers. 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)
