RFR: 8074457: Remove the non-Zero CPP Interpreter

[Coleen Phillimore]

Summary: Remove cppInterpreter assembly files and reorganize 
InterpreterGenerator includes

This change is mostly removal and removing the InterpreterGenerator 
class and making class Interpreter a typedef.  I removed conditional 
includes from interpreter header files in favor of small sections with 
ifdefs.   Many interpreter functions are still in the wrong cpp files 
but I want to leave that for a follow on, to not overwhelm reviewers.  
This is Large but not difficult to review.  There is also more purging 
that can be done with Zero, but I also want to leave that as a follow on 
RFE.

This has been tested with RBT (most of runtime tests on x86 and sparc), 
JPRT and builds zero with debug/fastdebug and product.

There are changes and deletions to ppc and aarch64.   Please let me know 
if you want to test with this patch or leave for follow on fixes.
