Enable inlining of trivial CoreBase methods

Summary: D22371899 et seq outlined part of the CoreBase implementation. However, in some cases (at least for opt builds), inlining trivial methods makes the code smaller. This comes from a combination of avoiding register spills and reducing exception handling code.

folly: use libiberty demangler to demangle Rust symbols

Summary:
- Use libiberty demangler for both folly::demangle variants
- Use built-from-source libiberty with uptodate Rust demangler
- Try Rust demangling before C++ demangling (since legacy Rust mangling looks
  like C++ mangling)

This uses some compile-time magic involving overload resolution to detect whether
`rust_demangle_callback` is declared. If not (ie, the libiberty hasn't been updated)
then it skips Rust demangling.
