Note that control flow instruction support isn't actually fully functional yet.

This replaces the old NQSSADCE code with the same functionality, but quite
different design. Instead of doing a single integerated pass, we now build
explicit data structures representing the dataflow.
This will enable analysis of flow control instruction, and could potentially
open an avenue for several dataflow based optimizations, such as peephole
optimization, fusing MUL+ADD to MAD, and so on.

In particular, this removes the dependency on prog_instruction, which
unfortunately creates some code duplication, but also opens a path towards
adding some hardware-specific things in there.

Adding constants is used in a number of non-native instruction
rewrites, and it required us to keep copies of modified gl_programs
around. This is a first step towards ending this.

This is just the first step of refactoring. The separation is not yet
clean enough with this commit.

This is all part of untangling the compiler from the classic driver, so that
it may be used in Gallium without depending on Mesa stuff if possible
