JDK-8245986 - AArch64: Provide information when hitting a HaltNode
Description
The code generated in MacroAssembler::stop is indeed grossly bloated with pusha()/popa() and a native call. We would like to follow JDK-8245986, and provide a halt reason when hitting a C2 HaltNode on riscv, and implement it by triggering illegal instruction exceptions.
