Refactor walkrange to treat "for _ = range a" as "for range a".
This avoids generating some later discarded nodes in the compiler.
Passes toolstash -cmp.

- removes the runtime function stringtoslicebytetmp
- removes the generation of calls to stringtoslicebytetmp from the frontend
- adds handling of OSTRARRAYBYTETMP in the backend
This reduces binary sizes and avoids function call overhead.

Details:
- reorder.go: delete p8.
(Once expectation is changed per b/4627 it is identical to p1.)
- switch.go: added some more (degenerate) switches.
- range.go: improved error messages in a few cases.
- method.go: added tests of calls to promoted methods.

for expr1, expr2 = range slice
was assigning to expr1 and expr2 in sequence
instead of in parallel. Now it assigns in parallel,
as it should. This matters for things like
for i, x[i] = range slice.
Fixes#3464.
