Description
What is the feature you'd like to have?
When inputting a function type, it would be nice to have the ability to set the return register(s?) via some syntax similar to the parameter register locations. Something like:
int32_t @ r14 my_func()
int32_t my_func() @ r14
Is your feature request related to a problem?
It would be nice to have a convenient way to do this.
Are any alternative solutions acceptable?
The only ways to do this are via the Edit Function Properties dialog or the api.

Research direction
Start by locating the type parser and the existing syntax for parameter register locations, then compare that behavior with the Edit Function Properties dialog and API mentioned in the issue. Define and implement accepted return-register syntax, including the intended handling of multiple return registers, and verify that parsed function types set the same locations as those existing interfaces.
