Avoid repeated forwarder_block_p calls in CFG cleanup

CFG cleanup maintains BB_FORWARDER_BLOCK and uses FORWARDER_BLOCK_P
to check that apart from two places which use forwarder_block_p
in outgoing_edges_match alongside many BB_FORWARDER_BLOCK uses.

The following adjusts those.

	* cfgcleanup.cc (outgoing_edges_match): Use FORWARDER_BLOCK_P.
