First noticed in a cube map shader from the DDK, guessed by analogy to
Bifrost, confirmed with computerator.

Hack because this bloats bi_instr and fails to model multiple staging
registers.

To be used for Valhall cycle counting.

We need this information for cycle counting in Valhall.

Allows calculating performance characteristics. Determined by feeding
crafting programs into Mali offline compiler (mostly as fragment
shaders, with a few OpenCL shaders used.)

These are required to lower the IR into something suitable for Valhall
packing.

Logic is lifted from bi_layout.c, adapted to work on instructions (not
clauses) and for Valhall's off-by-one semantic which is annoyingly
different than Bifrost. (But the same as Midgard -- Bifrost was
annoyingly different than Midgard!)

Valhall removes certain instructions from Bifrost, requiring a canonical
lowering.

Valhall has a lookup table for common constants. Add a pass to take
advantage of it, lowering away immediate indices.
