RFR(M): 8050942 : PPC64: implement template interpreter for ppc64le

[Lindenmaier, Goetz]

Hi Sasha,

I tested your change.  Unfortunately it breaks our port.  You need to fix Unsigned to 
Signed:

   if (ProfileInterpreter) {
     __ profile_switch_default(Rdef_offset_addr, Rcount/* scratch */);
     __ b(Lcontinue_execution);


If you want to, you can move loading the bci in this bytecode behind the loop.

Could you please fix indentation of relocInfo::none in call_c? Should
be aligned to call_c.

Best regards,
  Goetz.

Hi,

Please review the patch that ports template interpreter to the
little-endian PowerPC64.
I have tested it on linuxppc64le.
I need a sponsor.
