JDK-8244949 - [PPC64] Reengineer assembler stop function
Description
While discussing the AArch64 implementation (JDK-8245986) we found further improvement oportunities:
- Emit pointer to message instead of loading it into a register.
- Use VMError::report_and_die version which shows disassembly.

In addition to that, we can encode the information if a message is provided into the trap instruction.
