Allow AArch64FastISel to degrade graceully in the presence of an MVT::i128
Currently AArch64FastISel crashes if it tries to extend an integer into an
MVT::i128. This can happen by creating 128 bit integers like so:
typedef unsigned int uint128_t __attribute__((mode(TI)));
typedef int sint128_t __attribute__((mode(TI)));
This patch makes EmitIntExt check for their presence and then falls back to
SelectionDAG.
Tests included.
