We compile package sort as part of the compiler bootstrap,
to make sure the compiler uses a consistent sort algorithm
no matter what version of Go it is compiled against.
(This matters for elements that compare "equal" but are distinguishable.)
Package sort was compiled in such a way as to disallow
sort.Slice entirely during bootstrap (at least with some compilers),
while cmd/internal/obj was compiled in such a way as to
make obj.SortSlice available to all compilers, precisely because
sort.Slice was not. This is all highly confusing.
Simplify by making sort.Slice available all the time.
Followup to CL 169137 and #30440
(and also CL 40114 and CL 73951).
