These should not be in a union together.

instruction is not emitted under any circumstances in the stable
branches]

Branch instructions can point to the last shader block, which might be
empty. In this case, the branch points to a clause that doesn't exists,
leading to INVALID_ENC faults when the GPU tries to jump to this clause.
Check if the block is a terminal block before updating the branch
offset: jumping/branching to NULL is equivalent to a shader termination,
so the default value of 0 works just fine for terminal branches.

The polygon list is written by tiler jobs and read by fragment ones,
and nothing should re-use the heap until the fragment job is done.
4fec6c9448 ("panfrost: Add the tiler heap to fragment jobs") fixed
this for the !multi-context case by adding the heap BO to fragment job.
But the tiler heap is shared accross contexts, and vertex/tiler+fragment
job submission is done through 2 separate ioctls, meaning that
vertex/tiler and fragment jobs from 2 different context might be
interleaved.
Add a lock at the device level to ensure tiler/vertex+fragment jobs are
submitted sequentially, with no other jobs using the same tiler heap
in-between.
