Building jvm with AOT but without JVMCI should fail at configure time

From Martin Buchholz (see JDK-8206113)
"If I try instead
 --with-jvm-features=-graal,-jvmci
I get
/home/martin/ws/jdk11/src/hotspot/share/utilities/macros.hpp:277:4: error: #error "Must have JVMCI for AOT"

---

If I try instead
 --with-jvm-features=-graal,-aot,-jvmci
the build succeeds, but attempts to run jtreg fail with:


java.lang.NullPointerException
Error: failed to get JDK properties for /home/martin/ws/jdk11/build/linux-x86_64-normal-server-release/images/jdk/bin/java -enablesystemassertions -Djava.library.path=/home/martin/ws/jdk11/build/linux-x86_64-normal-server-release/images/jdk/../test/jdk/jtreg/native; exit code 1

All of these configure variants should Just Work.

From Vladimir

Yes, it should be config error.
We seems missing check HOTSPOT_CHECK_JVM_FEATURE(jvmci) in autoconf/hotspot.m4 when setting ENABLE_AOT.
