Check VSC_SIZE/VSC_SIZE2 regs from cmdstream to detect overflow, and
skip use of VSC visibility stream when overflow is detected, to avoid
GPU hangs.  This is done w/ introduction of some CP_REG_TEST/

In addition, eventually (after a frame or two) detect the condition and

panfrost: Feed compute shaders into the compiler

The path for compute shader compiles resembles the graphic shader
compile path, although it is substantially simpler as we don't need any
shader keying.

panfrost: Explain and include compute FBD

Squint at it hard enough and you realize it's the beginning of an
SFBD... I guess...

A compute shader with register spilling would be able to confirm this,
but we would expect to see the first field | 1 and an address splattered
later, setting up TLS.
