freedreno/ir3: convert scheduler back to recursive algo

I've played with a few different approaches to tweak instruction
priority according to how much they increase/decrease register pressure,
etc.  But nothing seems to change the fact that compared to original
(pre-multiple-block-support) scheduler, in some edge cases we are
generating shaders w/ 5-6x higher register usage.

The problem is that the priority queue approach completely looses the
dependency between instructions, and ends up scheduling all paths at the
same time.

Original reason for switching was that recursive approach relied on
starting from the shader outputs array.  But we can achieve more or less
the same thing by starting from the depth-sorted list.

shader-db results:

total instructions in shared programs:          113350 -> 105183 (-7.21%)
total dwords in shared programs:                219328 -> 211168 (-3.72%)
total full registers used in shared programs:   7911 -> 7383 (-6.67%)
total half registers used in shader programs:   109 -> 109 (0.00%)

    helped           0         322           0         711         215
      hurt           0         163           0          38           4

The shaders hurt tend to gain a register or two.  While there are also a
lot of helped shaders that only loose a register or two, the more
complex ones tend to loose significanly more registers used.  In some
more extreme cases, like glsl-fs-convolution-1.shader_test it is more
like 7 vs 34 registers!
