Fix the ARM tablegen files to output certain instructions in an alternate
syntax
The assembler currently shipping on OSX with xcode fails to compile some VFP
instructions when using a particular syntax, this patch works around those bugs
by outputting the same instructions in a syntax that the assembler can handle
correctly. I assume (although haven't verified) that gcc must not be using the
syntax llvm currently uses or it would also be producing invalid code when
compiling for armv6 with vfp enabled.
