lsl by 2 requires a number sign for xcode on ios 64 bit build.  add the # sign for ios compatibility.  remove legacy x86 asm files that are unused.  the unused files cause complications in build systems that build all files.

Enable assembly for clangcl build on Windows.  Previously assembly was disabled so clangcl would work, but only with C code.  As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both.  In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel.
