compiler: Rewrite do-while loops as while loops
This works around a Mac driver shader compiler bug that makes many
do-while loops cause GPU-hangs when ran.

Remove rx::ShaderSh and move the shared code to the GL.
The GL layer can interact with the translator directly, to query all
the active shader variables and call ShCompile.

Make a shader Shader::Data state structure.
This design follows the similar designs for Program, Framebuffer, etc.
Because of the current design, share a mutable pointer with the Impl
so the patch becomes a bit smaller and easier to review. In a follow-
up patch we can move the shared code into the GL layer.

Add an interm ShaderSh class.
This class logic will eventually move to the GL layer. Keep it
in the Renderer layer for now for refactoring purposes.

Remove CompilerImpl and merge code to gl::Compiler.
This class uses no Impl-specific code. We can also do a similar
code relocation for the gl::Shader class, but in several steps
because it is a bit more complex.

Make PackedVarying a D3D-only type.
The register assignment stuff only applies to the D3D back-end.
Cleans up the GL back-ends use of PackedVarying, and will lead
to future cleanups relating to packing varyings.

Make output variables part of Program's shared data.
Also initialize this structure within Program instead of DynamicHLSL.
This should have benefits for other back-ends. Also these variables
weren't being serialized and de-serialized with the program binary,
which could mess up WebGL apps that use MRT.
