[PATCH] Fix ICE with profiling

[Richard Guenther]

This fixes an ICE with value-profiling which happens because SSA
operands are not up-to-date when updating SSA form.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

	the stmt.
	(gimple_mod_pow2_value_transform): Likewise.
	(gimple_mod_subtract_transform): Likewise.
