This contains the part of D62225 which prevents insertion of lifetime intrinsics when creating the AlwaysInliner. This fixes the following tests when the new PM is enabled by default: Clang :: CodeGen/aarch64-neon-across.c Clang :: CodeGen/aarch64-neon-fcvt-intrinsics.c Clang :: CodeGen/aarch64-neon-fma.c Clang :: CodeGen/aarch64-neon-perm.c Clang :: CodeGen/aarch64-neon-tbl.c Clang :: CodeGen/aarch64-poly128.c Clang :: CodeGen/aarch64-v8.2a-neon-intrinsics.c Clang :: CodeGen/arm-neon-fma.c Clang :: CodeGen/arm-neon-numeric-maxmin.c Clang :: CodeGen/arm-neon-vcvtX.c Clang :: CodeGen/avx-builtins.c Clang :: CodeGen/builtins-ppc-p9vector.c Clang :: CodeGen/builtins-ppc-vsx.c Clang :: CodeGen/lifetime.c Clang :: CodeGen/sse-builtins.c Clang :: CodeGen/sse2-builtins.c Differential Revision: https://reviews.llvm.org/D63153 llvm-svn: 363277
