[foreign-abi] RFR: 8256080: AArch64: fatal error with unexpected intrinsic id _linkToNative [v2]

[Nick Gasson]

> AArch64 doesn't implement linkToNative yet. However during VM startup
> several of the MethodHandles methods are called with the _linkToNative
> intrinsic ID. Add minimal handling of this (taken from x86) to avoid
> fatal errors.

Nick Gasson has updated the pull request incrementally with one additional commit since the last revision:
