update the current basic block in addition to the current insert

ARM has to provide its own TargetLowering::findRepresentativeClass because its scalar floating point registers alias its vector registers.

early makes testing more annoying.

 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64.

This property will be used by the register pressure tracking instruction scheduler.

 - Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.
