Change native function call stubs to use JIT operations instead of ctiVMHandleException
https://bugs.webkit.org/show_bug.cgi?id=122982

Reviewed by Geoffrey Garen.

Change ctiVMHandleException to operationVMHandleException.  Change all exception operations to
return the catch callFrame and entryPC via vm.callFrameForThrow and vm.targetMachinePCForThrow.
This removed calling convention headaches, fixing https://bugs.webkit.org/show_bug.cgi?id=122980
in the process.
