cmd/compile: change StaticCall to return a "Results"
StaticLECall (multiple value in +mem, multiple value result +mem) ->
StaticCall (multiple ergister value in +mem,
multiple register-sized-value result +mem) ->
ARCH CallStatic (multiple ergister value in +mem,
multiple register-sized-value result +mem)
But the architecture-dependent stuff is indifferent to whether
it is mem->mem or (mem)->(mem) until Prog generation.
Deal with OpSelectN -> Prog in ssagen/ssa.go, others, as they
appear.
For #40724.
