radv: allow TC-compat HTILE with GENERAL outside of render loops

This gives +8% with Wolfeinstein Youngblood on my Vega64, and
according to someone else, it also improves performance with Doom
2016 and Wolfenstein 2 (and probably other ID Tech games).

This improvement is because Youngblood uses GENERAL for the main
depth-only pass and TC-compat HTILE is now enabled with GENERAL if
we know that we are outside of a render loop. This obviously also
reduces the number of HTILE decompressions from/to GENERAL.

Note that Youngblood violates the Vulkan spec regarding render loops
because they are only allowed with input attachments. Expect possible
rendering issues if apps use render loops with the wrong way (ie.
without input attachmens) because HTILE might not be coherent if
a depth-stencil texture is sampled and rendered in the same draw.

gitlab-ci: Run merge request pipelines automatically only for Marge Bot

MR pipelines not triggered by Marge Bot can still be triggered manually.

Motivation: The main & forked Mesa project CI pipelines combined are
currently generating over 1 TB of egress traffic per week. ~80% of this
is from pre-merge pipelines. Assuming this corresponds to 4 pre-merge
and one post-merge pipeline per MR on average, this change could
potentially eliminate up to ~60% of the overall traffic (by preventing
3 of the 4 pre-merge pipelines from running automatically).

(Of course, this could be subverted if all jobs of the other pipelines
were triggered manually anyway... In most cases, manually triggering
just a few jobs should suffice)

  do the trick.

anv/gen12: Lower VK_KHR_multiview using Primitive Replication

Identify if view_index is used only for position calculation, and use
Primitive Replication to implement Multiview in Gen12.  This feature
allows storing per-view position information in a single execution of
the shader, treating position as an array.

The shader is transformed by adding a for-loop around it, that have an
iteration per active view (in the view_mask).  Stores to the position
now store into the position array for the current index in the loop,
and load_view_index() will return the view index corresponding to the
current index in the loop.

The feature is controlled by setting the environment variable
ANV_PRIMITIVE_REPLICATION_MAX_VIEWS, which defaults to 2 if unset.
For pipelines with view counts larger than that, the regular
instancing will be used instead of Primitive Replication.  To disable
it completely set the variable to 0.

v2: Don't assume position is set in vertex shader; remove only stores
    for position; don't apply optimizations since other passes will
    do; clone shader body without extract/reinsert; don't use
    last_block (potentially stale). (Jason)

    Fix view_index immediate to contain the view index, not its order.
    Check for maximum number of views supported.
    Add guard for gen12.

v3: Clone the entire shader function and change it before reinsert;
    disable optimization when shader has memory writes. (Jason)

    Use a single environment variable with _DEBUG on the name.

v4: Change to use new nir_deref_instr.
    When removing stores, look for mode nir_var_shader_out instead
    of the walking the list of outputs.
    Ensure unused derefs are removed in the non-position part of the
    shader.
    Remove dead control flow when identifying if can use or not
    primitive replication.

v5: Consider all the active shaders (including fragment) when deciding
    that Primitive Replication can be used.
    Change environment variable to ANV_PRIMITIVE_REPLICATION.
    Squash the emission of 3DSTATE_PRIMITIVE_REPLICATION into this patch.
    Disable Prim Rep in blorp_exec_3d.

v6: Use a loop around the shader, instead of manually unrolling, since
    the regular unroll pass will kick in.
    Document that we don't expect to see copy_deref or load_deref
    involving the position variable.
    Recover use_primitive_replication value when loading pipeline from
    the cache.
    Set VARYING_SLOT_LAYER to 0 in the shader.  Earlier versions were
    relying on ForceZeroRTAIndexEnable but that might not be
    sufficient.
    Disable Prim Rep in cmd_buffer_so_memcpy.

v7: Don't use Primitive Replication if position is not set, fallback
    to instancing; change environment variable to be
    ANV_PRIMITVE_REPLICATION_MAX_VIEWS and default it to 2 based on
    experiments.

intel/fs: Allow multiple slots for position

Change brw_compute_vue_map() to also take the number of pos slots.  If
more than one slot is used, the VARYING_SLOT_POS is treated as an

When using Primitive Replication, instead of a single position, the
VUE must contain an array of positions.  Padding might be
necessary (after clip distance) to ensure rest of attributes start
aligned.

v2: Add note about array in the commit message and assert that

additional geometry-specific consts that link primitive/vertex stride

used by the vs to determine where to stlw outputs and used by the gs
to determine where to ldlw those outputs from.

FD emits these consts in the draw call because in GL, you can mix
and match shaders in different programs. In Vulkan, however, we
compile and link the shaders at pipeline creation, so we can emit

When NGG is used, vertex and tess eval shaders are executed on the

must perform:

* Request GS space using GS_ALLOC_REQ
* Export the primitive
* Finally, export the normal VS outputs

In this commit, two modes are implemented:

* "late" which matches what the RADV LLVM backend currently does
* "early" which is an optimized version as seen in radeonsi

Vulkan doesn't allow the shader to write the edge flags, so we can
currently always use the "early" mode.
