Introduce a new demangling function that supports symbols using Itanium mangling and Rust v0 mangling, and is expected in the near future to include support for D mangling as well. Unlike llvm::demangle, the function does not accept extra underscore decoration. The callers generally know exactly when symbols should include the extra decoration and so they should be responsible for stripping it. Functionally the only intended change is to allow demangling Rust symbols with an extra underscore decoration through llvm::demangle, which matches the existing behaviour for Itanium symbols.
