6eb2b1354b Replace fancy use of initializer lists with simple functions that return
vectors, and move this test code into an anonymous namespace.

Hoping that this will avoid hitting an MSVC bug that causes it to crash
and burn pretty spectacularly. Also, this degree of clever use of
initializer lists seems somewhat questionable in general. ;]

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.
