Fix operationCreateThis with exception return registers
https://bugs.webkit.org/show_bug.cgi?id=275082
rdar://problem/129190985
Reviewed by Yusuke Suzuki.
Because of the way we forward exception status to JIT code doesn't play
necessarily
nicely with DeferTermination at the top level of an operation. This is because
the
destructor of DeferTermination runs after we've initialized our exception
register.
While not a semantic issue this breaks tests in RELEASE+ASSERT builds.
