[X86] Add some early DAG combines to turn v4i32 AND/OR/XOR into FAND/FOR/FXOR whe only SSE1 is available.
v4i32 isn't a legal type with sse1 only and would end up getting scalarized otherwise.
This isn't completely ideal as it doesn't handle cases like v8i32 that would get split to v4i32. But it at least helps with code written using the clang intrinsic header.
