Give an error for each attempt to define a method on a builtin type.
Adjust error messages to be closer to gc error messages.
With these changes gccgo passes current tests on dev.typealias branch.
This changes the errors printed for test/fixedbugs/issue5089.go, but
the change is an improvement:
Before:

compiler, runtime: align gc data for m68k
The current GC requires that the gc data be aligned to at least a 4
byte boundary, because it uses the lower two bits of the address for
flags (see LOOP and PRECISE in runtime/mgc0.c). As the gc data is
stored as a [...]uintptr, that is normally always true. However, on
m68k, that only guarantees 2 byte alignment. Fix it by forcing the
alignment.
The parfor code used by the current GC requires that the parfor data
be aligned to at least an 8 byte boundary. The code in parfor.c
verifies this. This is normally true, as the data uses uint64_t
values, but, again, this must be enforced explicitly on m68k.
Fixes GCC PR 79037.
