76fc2d077f R600: Use bottom up scheduling algorithm

21ca0b3ea4 R600: Use depth first scheduling algorithm 
It should increase PV substitution opportunities and lower gpr
usage (pending computations path are "flushed" sooner)

4ed9917147 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.

152ebee8f3 R600: If previous bundle is dot4, PV valid chan is always X
