While playing with the css jit I noticed that sdiv is very similar on APPLE_ARMV7S and ARM64. Why not unite this code?

Comment on attachment 233074 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=233074&action=review > Source/JavaScriptCore/assembler/ARMv7Assembler.h:1520 > + COMPILE_ASSERT(datasize == 32); Does this compile? I mean, COMPILE_ASSERT() takes two arguments: a predicate and a error message to be shown if the predicate evaluates to false. Moreover, the blog post <https://www.webkit.org/blog/3172/webkit-and-cxx11/> implies that we should explicitly use static_assert() in new C++ code instead of the COMPILE_ASSERT() macro function (even though it calls through to static_assert()) since we require ports to build WebKit with compilers that supports the C++11 static_assert feature.

(In reply to comment #3) I'll use static_assert and double check that it compiles.
