freedreno/a3xx: only emit dirty consts

If app only updates (for example) vertex uniforms, it would be nice to
only re-emit those and not also frag uniforms.  Means we need to mark
the first frag shader const buffer dirty after a clear.

freedreno/ir3: fix potential gpu lockup with kill

It seems like the hardware is unhappy if we execute a kill instruction
prior to last input (ei).  Probably the shader thread stops executing
and the end-input flag is never set.

freedreno/ir3: add debug flag to disable cp

vc4: Don't look at back stencil state unless two-sided stencil is enabled.

Fixes regressions in the next bugfix, because gallium util stuff leaves
the back stencil state as 0 if !back->enabled.
vc4: Fix stencil writemask handling.

If the writemask doesn't compress, then we want to put in the uncompressed
writemask, not the compressed writemask failure value (all-on).

Fixes glean's stencil2 and fbo-clear-formats on stencil.
vc4: Fix SRC_ALPHA_SATURATE blending.

Fixes glean blendFunc.
gallium: add PIPE_SHADER_CAP_MAX_OUTPUTS and use it in st/mesa

With 5 shader stages and various combinations of enabled and disabled shaders,
the maximum number of outputs in one shader doesn't have to be equal to
the maximum number of inputs in the following shader.

v2: return 32 for softpipe and llvmpipe
st/mesa: add ST_DEBUG=wf option which enables wireframe rendering

Useful for tessellation.
glsl_to_tgsi: fix the value of gl_FrontFacing with native integers

We must convert it to boolean from the DX9 float encoding that Gallium
specifies.

Later, we should probably define that FACE should be 0 or ~0 if native
integers are supported.

radeonsi: inline si_pm4_alloc_state

It seemed like the function needed a context pointer. Let's remove it
to make it less confusing.

radeonsi: make pm4 state generation for shaders independent of the context

The si_pm4_delete_state calls became useless, because the pm4 state is
always generated only once.
