This patch is in response to r223147 where the avaiable features are computed based on ".cpu" directive. This will work clean for the standard variants like cortex-a9. For custom variants which rely on standard cpu names for assembly, the additional features of a CPU should be propagated. This can be done via ".arch_extension" as long as the assembler supports it. The implementation for krait along with unit test will be submitted in next patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230650 91177308-0d34-0410-b5e6-96231b3b80d8
