RFR: 8258856: VM build without C1/C2 fails after JDK-8243205

Wed Dec 23 05:53:04 UTC 2020

The declaration sites for JVM flags were changed by JDK-8243205 and the
subsequent JDK-8258074. As a result, undeclared identifier errors
occurred while building VM without compiler1 or compiler2 feature.

Making the corresponding header files included would fix it.

Note that we have tested locally with this patch, build without C1/C2 succeeded on Linux X86/AArch64 machines.
