Abstract PHI and forwarder block checks in jump threader.
This patch abstracts out a couple common idioms in the forward
threader that I found useful while navigating the code base.
Tested on x86-64 Linux.
gcc/ChangeLog:
* tree-ssa-threadedge.c (has_phis_p): New.
(forwarder_block_p): New.
(potentially_threadable_block): Call forwarder_block_p.
(jump_threader::thread_around_empty_blocks): Call has_phis_p.
(jump_threader::thread_through_normal_block): Call
forwarder_block_p.
