libgo: fix build when using -enable-static=no
With -enable-static=no we don't build non-pic objects, but libgotool.a
is built from non-pic objects. Build the packages that go into
libgotool.a in static mode in all cases.
Also ensure that internal test packages are built, since nothing
explicitly depended on them.

rs6000: Don't touch below the stack pointer (PR77687)
With the 32-bit SVR4 ABI we don't have a red zone, so we have to restore
the callee-saved registers before we restore the stack pointer.
The previous fix for this PR failed in two ways, for huge frames: first,
we use a negative offset from r11 in that case, so the (mem:BLK 11) access
does no good; second, sched does not handle accesses to mem:BLK correctly
in this case (does not make dependencies).
This patch fixes it by doing a store to (mem:BLK (scratch)) instead.
This means no unrelated (not to stack) loads/stores can be moved over the
stack restore either, but so be it.

runtime: restore "goroutine in C code" message
In the 1.9 upgrade I took out the word "goroutine" from a traceback
showing a goroutine running in C code, to let TestCgoNumGoroutine
pass. However, it turns out that some code is actually checking for
that string; for example,
https://github.com/grpc/grpc-go/blob/master/test/leakcheck/leakcheck.go#L44
So keep the message the same, and change the test.

The vectoriser was calling vect_get_smallest_scalar_type without

anyway. But it's not possible to tell which mask type the caller needs

In case OP is an invariant or constant, a new stmt that creates a vector def
