i965: Switch to NIR for ldexp lowering.

The old GLSL IR based lowering doesn't quite work right in all cases,
and fails several dEQP-GLES31 and Vulkan CTS tests.  Jason's new
approach in NIR passes all the tests.  There's not likely to be a ton
of advantage to lowering early in GLSL IR anyway, so...switch.
