When closing untagged template string literals, create a single n-ary
addition operation, instead of a tree of binary operations.
As a clean-up, this also entirely removes the "second" field from n-ary
operations. This was proving to be too confusing an API when building
an n-ary operation incrementally from a single expression (rather than
converting a binary operation).

Use an upper limit search followed by a binary search in the expression
depth test. As our maximum expression depths increase, a simple linear
search wastes cycles.

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.

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.

to group only related benchmarks together. This also makes it easier
