in an enabled-checking compiler gcc_checking_assert is always executed.
If that depends on things having happened under flag_checking being true,
but it's actually false during runtime due to -fno-checking things go
awry, like segfaulting in this case.  The fix is obvious and checked in
after regstrapping on x86_64-linux.


Ciao,

	* fwprop.c (update_uses): Use flag_checking instead of
	gcc_checking_assert.
