[MinGW] [AArch64] Add stubs for potential automatic dllimported variables The runtime pseudo relocations can't handle the AArch64 format PC relative addressing in adrp+add/ldr pairs. By using stubs, the potentially dllimported addresses can be touched up by the runtime pseudo relocation framework. Differential Revision: https://reviews.llvm.org/D51452 llvm-svn: 341401

[GlobalISel] Add ISel support for @llvm.lifetime.start and @llvm.lifetime.end 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
