RFR: 8315818: vmTestbase/nsk/jvmti/Allocate/alloc001/alloc001.java fails on libgraal

[Doug Simon]

This PR modifies eager JVMCI initialization such that a failure is logged but otherwise ignored if the initialization is solely for the purpose of `-Xcomp`.

This allows tests such as `vmTestbase/nsk/jvmti/Allocate/alloc001/alloc001.java` to succeed on libgraal, even when there is insufficient virtual memory to mmap libgraal.

-------------

Commit messages:
 - allow eager JVMCI initialization to fail if only done for -Xcomp
 - fix spelling
