Fix various JNI compiler bugs/unimplementeds.

For both x86 and arm we were under computing the outgoing argument size.
For ARM the managed double/long passing had been assumed to be following AAPCS,
however, currently we split long/doubles across R1_R2 and R3 and the stack.
Add support for this in the managed register and jni compiler code.
Add test and various other clean ups to jni compiler code.
