Fixes #23053. Two small bugs here: - the existing condition for printing out the group header was broken. it worked in the reproducer (in the issue above) without filtering only by accident, due to setting `self.has_ungrouped = true` once we see the warmup bench. Knowing that we sort benchmarks to put ungrouped benches first, there are only two cases: 1) we are starting the first group 2) we are ending the previous group and starting a new group - when you passed `--filter` we were applying that filter to the warmup bench (which is not visible to users), so we suffered from jit bias if you were filtering (unless your filter was `<warmup>`) TLDR; Running ```bash deno bench main.js --filter="G" ``` ```js // main.js Deno.bench({ group: "G1", name: "G1-A", fn() {}, }); Deno.bench({ group: "G1", name: "G1-B", fn() {}, }); ``` Before this PR: ``` benchmark time (avg) iter/s (min … max) p75 p99 p995 --------------------------------------------------------------- ----------------------------- G1-A 303.52 ps/iter3,294,726,102.1 (254.2 ps … 7.8 ns) 287.5 ps 391.7 ps 437.5 ps G1-B 3.8 ns/iter 263,360,635.9 (2.24 ns … 8.36 ns) 3.84 ns 4.73 ns 4.94 ns summary G1-A 12.51x faster than G1-B ``` After this PR: ``` benchmark time (avg) iter/s (min … max) p75 p99 p995 --------------------------------------------------------------- ----------------------------- group G1 G1-A 3.85 ns/iter 259,822,096.0 (2.42 ns … 9.03 ns) 3.83 ns 4.62 ns 4.83 ns G1-B 3.84 ns/iter 260,458,274.5 (3.55 ns … 7.05 ns) 3.83 ns 4.45 ns 4.7 ns summary G1-B 1x faster than G1-A ``` |

Deno CLI Crate
This provides the actual deno executable and the user-facing APIs.
The deno crate uses the deno_core to provide the executable.
