RFR: JDK-8292769: [JVMCI] OutOfMemoryError thrown when attaching the libgraal isolate causes HotSpot to crash. [v2]

[Tomáš Zezula]

> Fixes a virtual machine crash when the libgraal isolate does not have enough heap memory available and its memory is exhausted. The [crash](https://bugs.openjdk.org/secure/attachment/100520/hs_err_pid679001.log) is caused by an unhandled `OutOfMemoryError` thrown in the isolate's `AttachCurrentThread`.
> The isolate's `AttachCurrentThread` is [fixed](https://github.com/oracle/graal/commit/62ede96fd3ddc9e5ddb4804ed369f61cfa0c0a21#diff-9eedff7eb9fceec5f37c48cf089ff8e24103279e1384a2c0fa1fc9446b5dc438)  to report an `OutOfMemoryError` using a `JNI_ENOMEM` result. This pull request aborts a compilation when `AttachCurrentThread` fails with `JNI_ENOMEM`.
