a130438e13 [test] Removed old output parsing functions.
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.

5da204c87c [wasm] [fuzzer] Avoid reuse of input data
I just fixed an annoying bug where I accidentally used DataRange more
than once, leading to endless recursion.
This CL avoids that by forbidding copying of DataRange. Instead, it's
mostly passed by reference now.

3ede348741 [mips][turbofan] Implement on-stack returns.
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.

5d10735e18 [arm64] Pad function arguments.
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.

26e21fa67a [bigint] Increase maximum length.
In a benchmark that I'm looking at, the numbers quickly overflow our
current limit.

This patch increases kMaxLength to the greatest value that's possible
without requiring further code changes.

aefc8a3153 [heap] fix regression on thread_times.key_silk_cases
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.

f687903383 Reland "[arm64] Preparation for padding of arguments"
This is a reland of bcf1172992

The test was timing out in no snapshot builds, as each CodeAssemblerTester
creates a new Context. Reduced the random iterations significantly.

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.

9c7b6e1e8a [arm][turbofan] Implement on-stack returns.
This is the implementation of crrev.com/c/766371 for arm.

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.

several stats at a given time (percent and count) on a per function or
byte basis:
- preparsing
- parsing
- eager/lazy compiling
- execution
