[qfcc] Allow more control of intrinsic functions

Browse source 
If `@intrinsic()` is followed by `[expr_list]` then those expresses will
be used to create the intrinsic rather than the function's parameters,
allowing for reordering, adding extra parameters or even complex
expressions.

However, only the parsing is implemented.
