ARM: move feature for Thumb2 pkhbt/pkhtb onto architectures. There's not much functional change, but it really is an architectural feature (on v6T2, v7A, v7R and v7EM) rather than something each CPU implements individually. The main functional change is the default behaviour you get when specifying only "-triple". llvm-svn: 276013

@ Instruction is "v6T2, v7" in ARMARM-AR, "v7em" in ARMARM-M. So it's
@ valid on everything v6t2 upwards, except v7m. Also apparently not on
@ v8m (going by present behaviour).
