Summary:
This makes us more compatible with MSVC 2012+ and fixes PR17748 where we
would give two tables the same name.

Rather than doing a fresh depth-first traversal of the inheritance graph
for every record's vbtables, now we memoize vbtable paths for each
record.  By doing memoization, we end up considering virtual bases of
subobjects that come later in the depth-first traversal.  Where
previously we would have ignored a virtual base that we'd already seen,
we now consider it for name mangling purposes without emitting a
duplicate vbtable for it.

Summary:
No functionality change.

This code should live here long-term because we should be able to use it
to compute correct vftable names.

It turns out that the most natural way to implement the naming algorithm
is to use a caching layer similar to what we already have for virtual
table info in VTableContext.  Subsequent changes will take advantage of
this to fix PR17748, where we have a vbtable name collision.

over to TypeTraitExpr.

The UTT/BTT/TT enum prefix and evaluation code is retained pending further

ExpectAndConsume: Diagnose errors automatically

 1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
    using the generic diagnostic descriptions added in r197972, eliminating another
    set of trivial err_expected_* variations while maintaining existing behaviour.

 2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
    family of functions are primitive parser operations that now have the
    well-defined property of operating on single tokens. Factoring out recovery
    exposes opportunities for more consistent and tailored error recover at the
    call sites instead of just relying on a bottled SkipUntil formula.
