Roman Divacky 2664ea938f 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.
