Overall, total test runtime that was wasted due to timeouts is 3420 seconds in
the last 2 weeks. Even with 4 retries, assuming all of them time out, needed
additional capacity is under 2 hours per week. Based on this analysis, I think
it's safe to land this CL.
Note that this is not intended as a long-term solution of the timeout problem,
but rather a temporary solution to prevent ongoing errors. Proper investigation
and correct long-term solution are still needed and tracked in the bug.

The serialize set of microbenchmarks serializes Error.stack of a
prepared set of error objects. When all objects have been serialized,
the benchmark then wrapped around and only accessed the resulting
string properties. This, of course, is a lot faster and benchmark
results are heavily fluctuating when the end is reached.
This CL fixes this by introducing a payload that should be similiar
to the specific workload, which is executed after the end is reached.

The spec specifies that a non-true return values from the trap functions
should be treated as error in the strict mode. With the new lazy feedback
effort inferring the language mode is expensive and causes regression on
these tests. Since the test doesn't actually need to test this, fixing
them to return true would help test the performance of calling the trap
without the unnecessary overhead of inferring the language mode.

The new ObjectPtr design makes non-inlined helper functions a little
more expensive because "this" is always a pointer where pass-by-value
would be more efficient, which is an issue for functions whose size puts
them right at the threshold of getting inlined or not. String::Get falls
into this category when called from RegExpFlagsFromString. In this case,
we can do even better than restoring inlineability by fine-tuning
the control flow a bit.
This should repair the regression in crbug.com/910573

This replaces Runtime_RunMicrotasks with Runtime_PerformMicrotaskCheckpoint.
RunMicrotasks forcibly runs Microtasks even when the microtasks are suppressed,
and may causes nested Microtasks in a problematic way. E.g. that confuses
v8::MicrotasksScope::IsRunningMicrotasks() and GetEnteredOrMicrotaskContext().
OTOH, PerformMicrotaskCheckpoint() doesn't run cause the failure as it
respects the microtask suppressions.
As all existing tests don't call RunMicrotasks() in the suppressed situation
(like Promise.resolve().then(()=>{%RunMicrotasks();})), this change should
not affect to these tests.

The new node is introduced for literal string addition and calling
String.prototype.concat in the typed lowering phase. It later might get optimized
away during redundancy elimination, keeping the performance of already existing
benchmarks with string addition. In case the operation is about to throw
(due to too long string being constructed) we just deoptimize, reusing
the interpreter logic for creating the error.
Modify relevant mjsunit and unit tests for string concatenation.

Since TypedArrays do not specify endianness, we can't compare
performance across both possible endiannesses, but this is better
