[Bug target/53975] [ia64] Target register of a speculative load moved to a branch register prior to the chk.s instruction

Ah, of course the "move branch register" instruction faults if the NaT bit of
the source register is set. So the recovery code is irrelevant, and this could
be a GCC bug. Need a test case to investigate, though...
