[demangler] Clean up the expression parser
This commit cleans up the expression parser, using a new style:
- parse* functions now return Node pointers.
- The mangled name is now held in Db and accessed with look() and consume()
- LLVM coding style
This style is meant to avoid the 2 most common types of bugs in the
old demanger, namely misusing the Names stack (ie, calling back() on
empty) and going out of bounds on the mangled name. I also think it
makes the demangler a lot cleaner.
