This somehow lacks a commit message?

> Tools/Scripts/run-jsc:56
>      $jsc = $debuggerCmd . " " . File::Spec->catfile(jscProductDir(), "jsc -- --useDollarVM=1 ") . "@ARGV";

Huh, this is not nice. "jsc -- --useDollarVM=1 " is not a path component. I'd suggest improving this line while at it.

> Tools/Scripts/run-jsc:62
>  $ENV{"DYLD_FRAMEWORK_PATH"} = $dyld;

Is this still needed?

Yeah, that's kinda weird. I'll fix.

I left it in case you have a custom debugger you want to use. It's also needed for the non-debugger case. Really though, I wanna know if there's a way to have the jsc binary specify where to find the library.

Technically, there's @rpath that can be embedded in Mach-O loader commands (`otool -l` to see those in existing binaries). 

That would be tricky, as I don't think that jsc is always at the same relative path to the framework in all CI and development scenarios. I think that your approach in this patch is better.
