d38d9505d1 Avoid specializing a variadic member template in a way that seems to not
agree with MSVC.

There isn't actually a need for specialization here as we can write the
code generically and just have a test that will fold away as a constant.

9c2e4f39bc Allow demangler's node allocator to fail, and bail out of the entire
demangling process when it does.

Use this to support a "lookup" query for the mangling canonicalizer that
does not create new nodes. This could also be used to implement
demangling with a fixed-size temporary storage buffer.

2ae8468bd1 Add data structure to form equivalence classes of mangled names.
Summary:
Given a set of equivalent name fragments, this mechanism determines whether two
mangled names are equivalent. The intent is to use this for fuzzy matching of
profile data against the program after certain refactorings are performed.
