Reviewed by Justin Michaud.

Enable the WASM LLInt on Windows. We use csr2 in place of ws1 as a
scratch register inside WebAssembly.asm on Windows, which needs to be
saved / restored on the stack.

A number of changes were required in offlineasm x86.rb for intel syntax
output.

Integer division / remainder operations had issues, which could be
caught by static asserts https://bugs.webkit.org/show_bug.cgi?id=203692

g_wtfConfigForLLInt is used to reference global wtf config, working
around global loading bug https://bugs.webkit.org/show_bug.cgi?id=175104
