Matt Arsenault 36094d788a R600: Permute operands when selecting legacy min/max
This gets the correct NaN behavior based on the compare type
the hardware uses. This now passes the new piglit test I have
for this on SI.

Add stricter tests for the operand order.

Matt Arsenault a0050b0961 R600/SI: Add intrinsics for various math instructions.
These will be used for custom lowering and for library
implementations of various math functions, so it's useful
to expose these as builtins.

Tom Stellard 0351ea2010 R600: Fix handling of NAN in comparison instructions
We were completely ignoring the unorder/ordered attributes of condition
codes and also incorrectly lowering seto and setuo.

Vincent Lejeune 4c81d4da6f R600: Use depth first scheduling algorithm
It should increase PV substitution opportunities and lower gpr
usage (pending computations path are "flushed" sooner)

Vincent Lejeune 519f21eed3 R600: Relax some vector constraints on Dot4.
Dot4 now uses 8 scalar operands instead of 2 vectors one which allows register
coalescer to remove some unneeded COPY.
This patch also defines some structures/functions that can be used to handle
every vector instructions (CUBE, Cayman special instructions...) in a similar
fashion.
