The go/build package does not know that gccgo's standard packages don't
have source, and will report an error saying that it can not find them.
Work around that in the cmd/go sources, since the go/build sources don't
currently have a list of standard packages.
This should get a real fix in the master sources, somehow.
Fixesgolang/go#16701.

In the PR we have a PARALLEL of a move and a compare (a "mr." instruction).
The compare is dead, so single_set on it returns just the move. Then,
simple_move_p returns true; but the instruction does need reloads in this
case. This patch solves this by making simple_move_p return false for
every multiple_sets instruction.
