Add symbol table function to get TFunction for a built-in op

Built-in function parameter qualifiers are stored in the symbol table.
Some AST traversers need the qualifier information for ops to
determine whether a node is being written to. Add an utility function
that maps a TIntermAggregate node to a symbol table entry, so that the
traversers can get to this information in a convenient way.

This will be necessary for adding more built-ins that have out
parameters from ESSL 3.10.
