Subject: [PATCH] Allow AArch64FastISel to degrade graceully in the presence of an MVT::i128

Currently when the AArch64FastISel encounters MVT::i128’s it crashes. As it turns out clang can be coerced into generating those through the use of __attribute__((mode(TI))). Since most of AArch64FastISel is unprepared to cope with i128 bit types this patch makes the extension code bail out and force AArch64 back into SelectionDAG when it sees one.
