Message:

Several fixes to get RuntimeR3 building on SPARC again (required for vbox-img used by the OVM folks):

1. Generic implementation for RTSystemIsInsideVM returning always false
2. Add non assembly version for the zero memory objects g_abRTZero* for use on non x86/amd64 architectures where we don't have yasm (The code is not compiled on x86/amd64 because of better optimized assembler variants available)
3. Compile fix for bignum.cpp on sparc64 (no idea whether it is correct)
4. Remove superfluous ASMByteSwapU64 in asm-fake.cpp (generic variant defined in include/iprt/asm.h)
