[gcjx] Patch: FYI: fix to method instantiation

[Tom Tromey]

I'm checking this in on the gcjx branch.

This fixes a small problem with method instantiation.
It is basically a hack -- we set descriptor for an instantiation of a
generic method to be the same as the signature of its parent.  This
lets bytecode generation emit the correct descriptor.

A better fix will be to introduce explicit generic method
instantiations, along with pointers to parent methods, followed by
fixes in code generation.  I'll do this at some later date.
