[Attributor] Cleanup `::initialize` of various AAs

This commit cleans up the ::initialize method of various AAs in the
following ways:
  - If an associated function is required, give up on declarations.
    This was discovered as a real problem when lots of llvm.dbg.XXX
    call sites were assumed `noreturn` until proven otherwise. That
    does not make any sense and caused huge regressions and missed
  - Require more associated declarations for function interface AAs.
  - Use the IRAttribute::initialize to determine if function interface
    AAs can be used in IPO, don't replicate the checks (especially
    isFunctionIPOAmendable) all over the place. Arguably the function
    declaration check should be moved to some central place to.

[Attributor][NFC] Improve check lines in depgraph.ll

This adds the check lines with -NEXT so we see any change in the future.

[ARM] Try to rematerialize VCTP instructions

We really want to try and avoid spilling P0, which can be difficult
since there's only one register, so try to rematerialize any VCTP
