commit e150cbf591759af10f3d57acbe0eb381aafa00de

tree-optimization/111039 - abnormals and bit test merging
The following guards the bit test merging code in if-combine against
the appearance of SSA names used in abnormal PHIs.
PR tree-optimization/111039
* tree-ssa-ifcombine.cc (ifcombine_ifandif): Check for
SSA_NAME_OCCURS_IN_ABNORMAL_PHI.
* gcc.dg/pr111039.c: New testcase.

tree-optimization/111070 - fix ICE with recent ifcombine fix
We now got test coverage for non-SSA name bits so the following amends
the SSA_NAME_OCCURS_IN_ABNORMAL_PHI checks.
PR tree-optimization/111070
* tree-ssa-ifcombine.cc (ifcombine_ifandif): Check we have
an SSA name before checking SSA_NAME_OCCURS_IN_ABNORMAL_PHI.
