LibIDL: Emit an error when two decls of the same function are present

Browse source 
Duplicates can show up when copy-pasting IDL snippets into existing IDL
files, and the resulting error is extremely useless and misleading.
This commit makes it so the parser catches these cases, and emits a more
helpful error like "Overload set 'instantiate' contains multiple
identical declarations".
