[JSC] Add IRDump option with JITDump
https://bugs.webkit.org/show_bug.cgi?id=309344
rdar://171891036
Reviewed by Keith Miller.
This patch adds useIRDump and irDumpDirectory options.
They are effective only when useJITDump is enabled.
When it is enabled, we generate IRDump, which is just a very simple
sequence of DFG IR as a file. And we also generate JITDump's
JITCodeDebugInfo with this file. This debug info can associate a JIT
code range to a file line & column. By using them, we associate JIT code
with this on-the-fly generated IRDump files so profiler can show samples
in IRDump as well.
