RFR: 8338156: Fix -Wzero-as-null-pointer-constant warnings in jvmciCompilerToVM.cpp

[Kim Barrett]

Please review this change to remove -Wzero-as-null-pointer-constant warnings
in jvmciCompilerToVM.cpp. We're changing uses of _0 suffixed exception macros
to instead use the corresponding _NULL suffixed macros where appropriate.

Testing: mach5 tier1
