Updated patch

- Rebased.
- Get rid of using DataLayout to determine the size of control modes. It limits the usage of the intrinsics to some extent, because an IR transformation that would create a call to `llvm.get.fpmode` or `llvm.set.fpmode` must somehow know the size for current target. But for the main use cases it should be enough, only TargetInfo needs to be extended so that clang could know the size.
- The test that checks default lowering was rewritten using `soft-float` option.
