974358a8c1 radv/llvm: add clip distance outputs manually if they're missing 
It's possible that undef is written to clip/cull distance outputs and
they're eliminated, and we never set any position export to done=1 because
outinfo->pos_exports was calculated with the expectation that clip/cull is
exported.

Eliminating the export and fixing the done=1 bit hangs because the
hardware is still expecting clip/cull distances.

Fixes dEQP-VK.rasterization.provoking_vertex.transform_feedback.first.line_list
hang with LLVM.

8fcb4aa0eb radv: compact MRTs to save PS export memory space 
If there are holes between color outputs (e.g. a shader exports MRT1,
but not MRT0), we can remove the holes by moving higher MRTs lower. The
hardware will remap the MRTs to their correct locations if we remove
holes in SPI_SHADER_COL_FORMAT but not CB_SHADER_MASK. This is good for
performance because the hardware will allocate less space for color
MRTs.

This also allows to remove even more unused color exports because we no
longer need to force previous targets to be non-zero. Only SotTR seems
affected from our fossils db.
