Recommit r248154: [ARM] Handle DSP feature as an ArchExtKind
Currently, the availability of DSP instructions (ACLE 6.4.7) is handled in a hand-rolled tricky condition block in lib/Basic/Targets.cpp, with a FIXME: attached. http://reviews.llvm.org/D12937 moved the handling of the DSP feature over to ARMTargetParser.def in LLVM, to be in line with other architecture extensions. This is the corresponding patch to clang, to clear the FIXME: and update the tests. Differential Revision: http://reviews.llvm.org/D12938 llvm-svn: 248521
