sema: create pointer-to-function type for exported functions

Browse Source 
After creating the function type IP entry, also create a
pointer-to-function type (*const fn(...) ...) matching what the Zig
compiler creates when taking the address of a function for @export.

For neghf2.zig (num_passing=4), gap shrinks from 861 to 860.
