Bypass Code Blocks Requiring VM Access for the JIT Server

[luke-li-2003]

Bypass the code that requires a VM read in constraintRecognizedMethod() under JITServer mode, to prevent an invalid class pointer being sent to the client and crashing the client.

LGTM.
In the future we may be able to do more.
J9VMJAVALANGINVOKEMETHODHANDLE checks a particular entry in J9JavaVM->jclConstantPool[]. The entry is supposed to be a j9class. If the entry is 0, the code resolves the class and populates the field. Once the entry is populated it keeps the same value.
A possible enhancement is: create a new frontend query. At the server, if the desired entry (cached) is NULL, send a message to the client and cache the received j9class pointer.
