Michael Gottesman 6570c169c0 Teach SILArgument how to determine if it is a function argument or not. ...

A SILArgument is a function argument if the argument's parent BB is the entry BB
of the function containing the argument.

This is an interesting distinction since function arguments have special
aliasing properties with respect to indirect arguments which normal basic block
arguments do not.
