The code for backwards-compatibility with ABI v1 didn't do too well with

This PR is an enhancement request to emit a DW_TAG_ptr_to_member_type

Here the issue was that require_complete_type doesn't do anything in

In templates, we do overload resolution and then throw away most of it,
going back to the pre-conversion arguments. But when the call returns a

This prepares things to share constant folding between passes
(CCP, FRE and VRP). It simplifies maybe_fold_reference making
sure to first canonicalize MEM_REFs and then call other folders.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.
