Description
If we change Vm_version::supports_cx8() code like so then C++ compiler will create smaller/faster code in callers of that function since the return value is a constant.
#ifdef SUPPORTS_NATIVE_CX8
static bool supports_cx8() {return true;}
#else
static bool supports_cx8() {return _supports_cx8;}
#endif
#ifdef SUPPORTS_NATIVE_CX8
static bool supports_cx8() {return true;}
#else
static bool supports_cx8() {return _supports_cx8;}
#endif
