Remove an unnecessary header from this file. I don't think this header was really intended, and it may have been required prior to some of the recent refactors. Including it however causes LLVMX86Desc to need symbols from LLVMX86CodeGen, forming a dependency cycle. This was masked in almost all builds: Clang, and GCC w/ optimizations didn't actually emit the symbols!
