compiler, runtime: Use function descriptors.
This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct. The first field of
the struct points to the function code. The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions. For each call to a function, the address of the
function descriptor is passed as the last argument.
This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.
