Avoid recomputing PHI results after failure (PR104203).
Resolves:
PR tree-optimization/104203 - huge compile-time regression in pointer_query
gcc/ChangeLog:
PR tree-optimization/104203
* gimple-ssa-warn-access.cc (pass_data pass_data_waccess): Use
TV_WARN_ACCESS.
* pointer-query.cc (access_ref::merge_ref): Change return type.
Convert failure to a conservative success.
(access_ref::get_ref): Adjust to the change above. Short-circuit
PHI evaluation after first failure turned into conservative success.
* pointer-query.h (access_ref::merge_ref): Change return type.
* timevar.def (TV_WARN_ACCESS): New timer variable.
