[JSC] Add dumpBytecodeProfile
https://bugs.webkit.org/show_bug.cgi?id=318649
rdar://181454253
Reviewed by Yusuke Suzuki.
Exposes Profiler::Database::save() as dumpBytecodeProfile(path). Lets JS
callers write the profiler state mid-run instead of only at atexit, which
can be used to dump iteration-0 bytecode profile data in JS3 — counters
are monotonic, so a snapshot at end of iteration 0 captures iter-0-only
execution counts.
No-op when jsc is run without `-p`.
