rc_get_readers_normal() supplies a list of readers for a given
instruction. This function is now being used by the copy propagate
optimization and will eventually be used by most other optimization
passes as well.

Wine likes to create a *lot* of constants, exceeding the size of the constant
file in hw.

This pass renames register in order to make it easier for the pair
scheduler to group TEX instructions together.
This fixes fdo bug #28606

The loop emulation unrolls loops as may times as possbile while still
keeping the shader program below the maximum instruction limit. At this
point, there are no checks for constant conditionals. This is only enabled
for fragment shaders.

Yes, I'm fully aware this generates subpar code on r500.

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
