middle-end/114070 - folding breaking VEC_COND expansion
The following properly guards the simplifications that move
operations into VEC_CONDs, in particular when that changes the
type constraints on this operation.
This needed a genmatch fix which was recording spurious implicit fors
when tcc_comparison is used in a C expression.
PR middle-end/114070
* genmatch.cc (parser::parse_c_expr): Do not record operand
lists but only mark operators used.
* match.pd ((c ? a : b) op (c ? d : e) --> c ? (a op d) : (b op e)):
Properly guard the case of tcc_comparison changing the VEC_COND
value operand type.
* gcc.dg/torture/pr114070.c: New testcase.
