[Bug middle-end/26977] [4.2 regression] ICE in emit_move_insn

Damn.  Unfortunately, although I have four different IA-64 boxes, one none
of them can I test Ada.  Is it possible to attach the traceback of the
failure to the bugzilla PR?  Clearly the fact that y is NULL_RTX at the
assertion is problematic, but I can't tell where the call to emit_move_insn
is coming from.  The new calls to emit_move_insn in the PR17959 fix both
pass the result from simplify_gen_subreg which should never return NULL,
i.e. the problematic call is probably not directly related to the change.

I'll start an ia64-unknown-linux-gnu bootstrap here anyway, just to see if
anything strange is happening in the testsuite.

Sorry for the inconvenience.
