Summary: Bug fixes for JKU coroutine
The JKU patch has several flaws:
1. When using JDI to debug coroutine, it may crash because the _switchTo intrinsic entry will change to the interpreter one, which is a SHOULD_NOT_REACH_HERE().
2. Change miscellaneous thread-local data structures to coroutine-local level during _switchTo phase.
3. Disable making zombies of _switchTo alike intrinsic things.
4. Fix multiple mem leak problems for coroutine data structures.
5. Create an empty JNIHandleBlock for the first Java call.
6. The stack layout of Coroutine doesn't align with 16 bytes on x86_64 which will cause some float point instructions to throw an sig fault.
7. etc.
