aco: reorder VMEM operands in ACO IR
...
For all VMEM instructions, the resource constant is now
in operands[0]. For MIMG instructions, the sampler shares
operands[1] with write data in case this instruction writes memory.
Moving the VADDR to be the last operand for MIMG is the first step to
support Navi NSA encoding.

aco: don't schedule instructions through depending VMEM instructions

Previously, the scheduler tried to move up instructions from below depending
VMEM instructions only to move them down again when scheduling the VMEM
instruction.

aco: only skip RAR dependencies if the variable is killed somewhere

This patch changes VMEM scheduling in a way that they can only
be moved upwards by previous VMEM instructions but not downwards.
This way, it improves the order of VMEM instructions in relation

aco: restrict scheduling depending on max_waves
...
Previously, we allowed all shaders to reduce the number of max_waves to as low as 5.
Restricting this on shaders with low register demand, increases the total number of waves
while the VMEM def-use distances hardly change.
This patch also changes the max number of move operations per MEM instruction.

aco: Initial commit of independent AMD compiler
...
ACO (short for AMD Compiler) is a new compiler backend with the goal to replace
LLVM for Radeon hardware for the RADV driver.
ACO currently supports only VS, PS and CS on VI and Vega.
There are some optimizations missing because of unmerged NIR changes
which may decrease performance.
