Adjust JIT categories for the latest JSC (#619)

This patch adds JSC JIT categories to samply. JSC's JITDump information
is updated and refactored, and they are now annotated with LinkBuffer's
type with `JSC-` prefix.

It seems that if they are recognized as is_js = true, profiler results
are showing stack entry twice for JSC. So we make all of them non JS.
