Transition cti_op_throw and cti_vm_throw to a JIT operation
​https://bugs.webkit.org/show_bug.cgi?id=122931

Reviewed by Filip Pizlo.

Moved cti_op_throw to operationThrow. Made the caller responsible for jumping to the
catch handler. Eliminated cti_op_throw_static_error, cti_vm_throw, ctiVMThrowTrampoline()
and their callers as it is now dead code. There is some work needed on the Microsoft X86
callOperation to handle the need to provide space for structure return value.
