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.
