Description
Due to some improvements to propagating self-referential functions, the user-provided sample of river gulf mounts functionally has its first function go from:
int64_t (*)() sub_100000000()
to:
int64_t (* (* (*)())())() sub_100000000()
when going from 5.3 to 6.0.

Research direction
Reproduce the user-provided river gulf mounts functionally sample under versions 5.3 and 6.0, then compare the first function's inferred type. Trace the self-referential function propagation responsible for the added dereferences. Done means the function remains int64_t (*)() rather than gaining the extra nested function-pointer levels.
