mergephi: Move checks from pass_merge_phi::execute to remove_forwarder_block_with_phi

This moves the checks that were in pass_merge_phi::execute into remove_forwarder_block_with_phi
or tree_forwarder_block_p to make easier to merge remove_forwarder_block_with_phi with remove_forwarder_block.
This also simplifies the code slightly because we can do `return false` rather than break
in one location.

gcc/ChangeLog:

	* tree-cfgcleanup.cc (pass_merge_phi::execute): Move
	check for abnormal or no phis to remove_forwarder_block_with_phi
	and the check on dominated to tree_forwarder_block_p.
	(remove_forwarder_block_with_phi): here.
