Fix discriminators of gimple PHI arguments

while gimple PHI itself does not have locations, the arguments does and they
can be used to determine count of edges in CFG.  Assign_discriminators already
knows how to handle goto_locus and PHI args should be handled same way as
done by this patch.

Bootstrapped/regtested x86_64-linux, comitted.

gcc/ChangeLog:

	* auto-profile.cc (function_instance::match): Sanity check
	that gimple PHI has no location.
	* tree-cfg.cc (assign_discriminators): Also remap locations
	of gimple PHI arguments.
