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

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.)

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.
Signed-off-by: Alyssa Rosenzweig <alyssa@collabora.com>

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

Uses the same set of cases. This is a standalone C program because the
easy way of hooking into the disassembler from Python with subprocesses
was slow. This seems cleaner anyway.

These are lines of assembly that look valid but are not, and should
raise a parser error but not otherwise crash the assembler or produce
invalid code.
