RFR: 8041794: remove bytecodes_<arch>.{cpp,hpp} files

[Lev Priima]

Hi,

Problem:
We don't have any platform specific bytecodes and these files are empty:
hs-comp/hotspot$ find -name bytecodes_\* | grep -v "/.hg/"
./src/cpu/ppc/vm/bytecodes_ppc.cpp
./src/cpu/ppc/vm/bytecodes_ppc.hpp
./src/cpu/sparc/vm/bytecodes_sparc.cpp
./src/cpu/sparc/vm/bytecodes_sparc.hpp
./src/cpu/x86/vm/bytecodes_x86.cpp
./src/cpu/x86/vm/bytecodes_x86.hpp
./src/cpu/zero/vm/bytecodes_zero.cpp
./src/cpu/zero/vm/bytecodes_zero.hpp

.hpp's are only included in bytecodes.hpp:
hs-comp/hotspot$ grep -rn \"bytecodes_\* src
src/share/tools/IdealGraphVisualizer/Data/src/com/sun/hotspot/igv/data/serialization/Parser.java:79: 
public static final String BYTECODES_ELEMENT = "bytecodes";
src/share/vm/interpreter/bytecodes.hpp:292:# include "bytecodes_x86.hpp"
src/share/vm/interpreter/bytecodes.hpp:295:# include "bytecodes_sparc.hpp"
src/share/vm/interpreter/bytecodes.hpp:298:# include "bytecodes_zero.hpp"
src/share/vm/interpreter/bytecodes.hpp:301:# include "bytecodes_arm.hpp"
src/share/vm/interpreter/bytecodes.hpp:304:# include "bytecodes_ppc.hpp"

All bytecodes_<arch>.cpp files have empty implementations of their 
functions.
Function:
src/share/vm/interpreter/bytecodes.hpp:335: static Code 
pd_base_code_for(Code code);
with empty implementation in each platform-specific bytecodes_* file is 
never called.


Solution:
I've removed these files and include directives of them. Also I removed 
two function declarations and one call-statement of pd_initialize().
