Only relevant for indirect contexts, so let's get that code out of the
common path.

From the MEDIA_VFE_STATE docs:

   "Starting with this configuration, the Maximum Number of Threads must
    be set to (#EU * 8) for GPGPU dispatches.

    Although there are only 7 threads per EU in the configuration, the
    FFTID is calculated as if there are 8 threads per EU, which in turn
    requires a larger amount of Scratch Space to be allocated by the
    driver."

It's pretty clear that we need to increase this for scratch address
calculations, because the FFTID has a certain bit-pattern.  The quote
above seems to indicate that we should increase the actual thread count
programmed in MEDIA_VFE_STATE as well, but we think the intention is to
only bump the scratch space.

Fixes GPU hangs in Bioshock Infinite and Synmark's CSDof on Icelake 8x8.

This reverts commit 729de148.

It turns out that, although the register is in the logical context,
it isn't whitelisted, so we can't actually write it from userspace
batch buffers.  The write just becomes a noop, which is why we saw
no performance changes.

I manually whitelisted it, and still observed no performance gains, but
it did regress KHR-GL46.texture_cube_map_array.color_depth_attachments
on the iris driver.  So we might need to fix something before enabling
this.  To prevent it randomly getting turned on should the kernel ever
whitelist this register, we revert the patch for now.

In a3268599, I attempted to fix nir_repair_ssa for unreachable
blocks.  However, that commit missed the possibility that the use is in
a block which, itself, is unreachable.  In this case, we can end up in
an infinite loop trying to replace a def with itself.  Even though a
no-op replacement is a fine operation, it keeps extending the end of the
uses list as we're walking it.  Instead of explicitly checking for the
group of conditions, just check if the phi builder gives us a different
def.  That's guaranteed to be 100% reliable and, while it lacks symmetry
with the is_valid checks, should be more reliable.

pipe->clear() is not called for partial clears, which mesa emulates by
drawing a quad.
Furthermore, drivers should not use rasterizer state information for
scissor information (which was being used to handle the partial clears).
So, remove the partial clear support since it was not supposed to be
handled by pipe->clear() anyway.
This fixes issues with clearing after switching to different sized
framebuffers.

Allocating BOs is expensive, so we should avoid doing that by caching
freed BOs.

BO cache is modelled after one in v3d driver and works as follows:

- in lima_bo_create() check if we have matching BO in cache and return
  it if there's one, allocate new BO otherwise.
- in lima_bo_unreference() (renamed from lima_bo_free()): put BO in
  cache instead of freeing it and remove all stale BOs from cache
