Bradley Smith 9f4cd59e80 [ARM] Fix subtarget feature set truncation when using .cpu directive
This is a bug that was caused due to storing the feature bitset in a 32-bit
variable when it is a 64-bit mask, discarding the top half of the feature set.

Roman Divacky 7e6b5955d4 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.
