ARM IAS: (partially) support .arch_extension directive This adds a partial implementation of the .arch_extension directive to the integrated ARM assembler. There are a number of limitations to this implementation arising from the target backend support rather than the implementation itself. Namely, iWMMXT (v1 and v2), Maverick, and XScale support is not present in the ARM backend. Currently, there is no check for A-class only (needed for virt), and no ARMv6k detection (needed for os and sec). The remainder of the extensions are fully supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201471 91177308-0d34-0410-b5e6-96231b3b80d8
