While preparing my patch to conditionally compile GCs, I see that there are some incorrect usages of INCLUDE_xxx checks in the Compiler code:
```$ grep -r "ifdef INCLUDE" src/hotspot/
src/hotspot/share/utilities/macros.hpp:#ifdef INCLUDE_AOT
src/hotspot/share/runtime/deoptimization.cpp:#ifdef INCLUDE_JVMCI
src/hotspot/share/runtime/java.cpp:#ifdef INCLUDE_JVMCI```
and:
```$ grep -r "ifndef INCLUDE" src/hotspot/
...
src/hotspot/share/runtime/deoptimization.cpp:#ifndef INCLUDE_JVMCI
src/hotspot/share/runtime/deoptimization.cpp:#ifndef INCLUDE_JVMCI
src/hotspot/share/runtime/deoptimization.cpp:#ifndef INCLUDE_JVMCI```

AFAICT, this is incorrect because ifdef INCLUDE_JVMCI will be true when INCLUDE_JVMCI is set to 0.
