micro-benchmark is missing from the resource files. On Android devices,
resources need to be whitelisted for loading. The missing resource file is

This CL removes the "PrepareElementsForSort" runtime function, and
replaces it with a simpler version in Torque. The biggest difference
is that certain sparse configurations no longer have a fast-path.
The Torque pre-processing step replaces the existing Torque mechanism that
copied already pre-processed elements into the "work" FixedArray. The Torque
compacting works as follows:
- Iterate all elements from 0 to {length}
- If the element is the hole: Do nothing.
- If the element is "undefined": Increment undefined counter.
- In all other cases, push the element into the "work" FixedArray.
Then the "work" FixedArray is sorted as before. Writing the elements from
the "work" array back into the receiver, after sorting, has three steps:
1. Copy the sorted elements from the "work" FixedArray to the receiver.
2. Add previously counted number of "undefined" to the receiver.
3. Depending on the backing store either delete properties or

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.
