  Log Message:
  -----------
  [AArch64] Don't look at type size for scalable types in isExtFreeImpl

This fixes one of those 'Request for a fixed element count on a scalable
object' errors in the AArch64 isExtFreeImpl method, where the uses of a sext
are checked to see if the instruction can be considered free.
