TargetMachine::getSubtargetImpl routines. This keeps the target independent code free of bare subtarget calls while the remainder of the backends are migrated, or not if they don't wish to support per-function subtargets as would be needed for function multiversioning or LTO of disparate cpu subarchitecture types, e.g. clang -msse4.2 -c foo.c -emit-llvm -o foo.bc clang -c bar.c -emit-llvm -o bar.bc llvm-link foo.bc bar.bc -o baz.bc llc baz.bc and get appropriate code for what the command lines requested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232885 91177308-0d34-0410-b5e6-96231b3b80d8
