RFR: 8276044: ciReplay: C1 does not dump a replay file when using DumpReplay as compile command option

[Christian Hagedorn]

This patch adds support to dump replay files for C1 with the compile command `DumpReplay`. I added a test to verify that a replay file is dumped with C1 (and C2).

Thanks,
Christian
