Add .machine directives for scv, copy, paste,  cpabort instructions

Add .machine directives for the scv, copy, paste, cpabort assembly instructions.

Hardware sync instruction (hwsync) added after the copy, paste and cpabort
instructions to improve the reliability of the test.

    powerpc: Add .machine directives for scv, copy, paste, cpabort instructions
    
    GCC is no longer passing the "-many" flag to the assembler.  So, the
    inline assembly instructions statements need to use the .machine directives
    for the specific platform.
    
    (gcc commit e154242724b084380e3221df7c08fcdbd8460674 ; "[RS6000] Don't
    pass -many to the assembler".
    
    Hardware sync instruction (hwsync) added after the copy, paste and cpabort
    instructions to improve the reliability of the test.
