tree-optimization/116057 - wrong code with CCP and vector CTORs
The following fixes an issue with CCPs likely_value when faced with
a vector CTOR containing undef SSA names and constants. This should
be classified as CONSTANT and not UNDEFINED.
PR tree-optimization/116057
* tree-ssa-ccp.cc (likely_value): Also walk CTORs in stmt
operands to look for constants.
* gcc.dg/torture/pr116057.c: New testcase.
