Simon Pilgrim 22d789345f [X86][SSE] Replace (V)CVTTPS2DQ and VCVTTPD2DQ truncating (round to zero) f32/f64 to i32 with generic IR (llvm)
This patch removes the llvm intrinsics (V)CVTTPS2DQ and VCVTTPD2DQ truncation (round to zero) conversions and auto-upgrades to FP_TO_SINT calls instead.

Note: I looked at updating CVTTPD2DQ as well but this still requires a lot more work to correctly lower.
