Declare the type of function entry points
This shuts off compiler warnings and will allow to enable stronger
compiler checks files that include beam_disasm.hrl in the hipe
application.
While doing that, also modified a comment in the header file and
turned a case statement into effectively an assertion: there should
not really be any beam files where functions do not have a label as
entry point, right?
