All get outcome logic moved out from testsuite which makes output
processors serializable. Output processors that are not global
are stored inside testcase to share them with all test copies.

This is the implementation of crrev.com/c/766371 for mips.
Original description:
Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.

This patch updates the instruction selector and code generator to pad arguments
for arm64 and drop an even number of slots when dropping the arguments. It also
updates the builtins that handle arguments. These changes need to be made at
the same time.
It also adds some tests for forwarding varargs, as this was affected by the
builtin changes and the existing tests did not catch all issues.

Doing an allocation step before the limit is picked is more correct, but
it causes the idle scavenger and incremental marking to run more
frequently, which causes a regression on certain thread_time benchmarks.
This CL fixes the regression by reverting the behaviour. A proper fix
can be implemented in a follow-on.

Original change's description:
> [arm64] Preparation for padding of arguments
>
> As part of JSSP removal, we need to align the arguments passed to functions
> on the stack, by adding a padding slot when the total number of arguments
> is odd.
>
> This patch introduces the kPadArguments flag (which is currently set to
> false for all architectures), which will control padding of arguments in
> architecture-independent parts of the code (deoptimizer, instruction
> selector).
>
> It also adds some executable tests for tail calls with various stack
> parameter counts on the caller and callee sides.
>
> This will be turned on for arm64 together with arm64-specific changes to
> the code generator, the MacroAsembler and the builtins, in a later patch.
