The score is computed based on how often the benchmark's function can
be run within one second. Simply importing a Module repeatedly doesn't
do any work, so to make the test score meaningful, we must wrap the
payload into a function that can be called explicitly for every run.

Also re-add a sanity check after the loop, and fix a missing variable add (a15)

The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.

This patch renames the FAST elements kinds as follows:

- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS

The following exceptions are left intact, for lack of a better name:

- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS

This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.

which can be nested before the compiler runs out of stack space.
This isn't really a performance test, but is created as a js-perf-test

All the bytecode handlers were added a one test, so we would get a
total on all of the bytecode handler benchmarks. It is not a good
indicator when we total unrelated benchmarks. So added more categories
to group only related benchmarks together. This also makes it easier
to look at the results.
