Demangle

[brenhinkeller]

This attempts to re-implement name demangling in a consistent way across all methods, plus a bit of general cleanup

There are some failures on Nightly that I'm not sure the deal with yet, will have to check if they are from this PR or not..

We could also think about whether we want to turn on demangling by default -- would arguably more convenient and logical long-term, though possibly technically a breaking change?

[tshort]

I'm fine with demangling by default.

[brenhinkeller]

Ok, looks like we have the same Nightly failures in https://github.com/tshort/StaticCompiler.jl/tree/rerun-ci (something to do with Nightly breaking LV / StrideArrays?) but I'll wait a day to see if it resolves itself

If folks are good with it, I'll plan to release this as 0.4.12 and then switch to demangling by default as 0.5.0 (and switch over StaticTools and examples to match)
