glsl: Make it possible to ignore built-ins when matching signatures.
Historically, we've implemented the rules for overriding built-in
functions by creating multiple ir_functions and relying on the symbol
table to hide the one containing built-in functions. That works, but
has a few drawbacks, so the next patch will change it.
Instead, we'll have a single ir_function for a particular name, which
will contain both built-in and user-defined signatures. Passing an
extra parameter to matching_signature makes it easy to ignore built-ins
when they're supposed to be hidden.
I didn't add the parameter to exact_matching_signature since it wasn't
necessary.
