failure to create a libgraal JavaVM should result in a VM crash

Creating a libgraal JavaVM instance can fail for two types of reasons:

1. The libjvmcicompiler.so file cannot be located or loaded, possibly due to an invalid value for the -XX:JVMCILibPath option.
2. An internal bug in libjvmcicompiler.so causing JNI_CreateJavaVM to fail.

Currently, both conditions result in a call to vm_exit_during_initialization which prints an error message and exits the VM process. For example:

Error occurred during initialization of VM
JNI_CreateJavaVM failed with return value -1000000007: /b/b/e/.tmp/tmpdpntkajk/graalvm/jre/lib/amd64/libjvmcicompiler.so

However, to investigate issues of type 2, it's usually useful to have a hs_err crash log. As such, these conditions should exit the VM with a call to fatal() so that a hs_err file is produced.
