Introduce CPUStringIsValid() into MCSubtargetInfo and use it for ARM .cpu parsing. Previously .cpu directive in ARM assembler didnt switch to the new CPU and therefore acted as a nop. This implemented real action for .cpu and eg. allows to assembler FreeBSD kernel with -integrated-as. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223147 91177308-0d34-0410-b5e6-96231b3b80d8 2014-12-02 20:03:22 +00:00			`// RUN: not llvm-mc -o - -triple arm-gnueabi-freebsd11.0 < %s > %t 2> %t2`
