When a resouce is already invalidated, its hash table entry becomes
useless. In addition, the lima_job_free() function won't remove the hash
table entry for invalidated resource. So the hash entry should be
removed when invalidating the resource, otherwise bogus hash entry might
be left in the table, and when the resource is reused in another job,
the code will find the freed job when invalidating and thus result in crash.

The load_store_vectorizer tests were using the specific memory
barriers, but since scoped barriers are also handled, prefer that.

Provide a generic interface which manages aux resolves in ISL. The
feature differences between this and what's in iris is:
* Support for media compression. ISL_AUX_USAGE_MC behaves differently
from many other usages of CCS, so it was useful to implement this
support upfront, while designing the interfaces.
* Optimizations for full-surface writes. For example, after a
full-surface write occurs with ISL_AUX_USAGE_CCS_E in the PARTIAL_CLEAR
state, isl_aux_state_transition_write() returns COMPRESSED_NO_CLEAR
instead of COMPRESSED_CLEAR.
A performance suggestion for main-surface-invalidating/replacing writes
is given as a comment instead of adding a boolean to
isl_aux_prepare_access(). This avoids extra validation and should be
simple enough for the caller to handle.

This lowers mediump FS outputs to fp16 in the ir3 backend. For now
this is a modest improvement, which mostly helps us whittle down the
full mediump work. Once the GLSL level support lands, then right hand
side of the store output intrinsics will be fp16 expressions and we'll
cancel out the fp16 -> fp32 -> fp 16 round trip here.
We've had different attempts at implementing this: rewriting stores in
the GLSL IR, lowering GLSL IR outputs to temporaries and inserting
conversions when writing the temporaries to the outputs. In the end,
GLSL ends up getting in the way a lot and doing it at the nir level is
easier and still possible since we have the output var precisions.
This part of the fp16 work is more of a step on the way towards full
fp16 support and will add a few extra conversion instructions:

This eliminates conversions between f16 and f32 where possible. We can
always remove an upcast followed by a down cast, that is:
f2f16 ( f2f32 (a) ) -> a
f2fmp ( f2f32 (a) ) -> a
In the other direction, f2f16 loses precision and can't be undone by a
f2f32. However, by definition it's always safe to elminate f2fmp:
f2f32 ( f2fmp (a) ) -> a

This pass tries to fold f2f16 conversion into alu instructions.
This will be useful to help reduce the number of instructions once
mesa starts supporting precision lowering. For example:
add.f r0.w, r0.w, c0.x
cov.f32f16 hr2.x, r0.w
to
add.f hr2.x, r0.w, c0.x
Additionally this pass also tries to fold f2f16 conversion into load_input
instruction:
bary.f r0.x, 3, r0.w
cov.f32f16 hr0.x, r0.x
to
bary.f hr1.x, 3, r0.x
v2: Edit to not fold OPC_MAX_F and OPC_MIN_F, since that's not valid.

This opcode is the same as the f2f16 opcode except that it comes with
a promise that it is safe to optimise it out if the result is
immediately converted back to a 32-bit float again. Normally this
would be a lossy conversion and so it would be visible to the
application, but if the conversion is generated as part of the mediump
lowering process then this removal doesn’t matter. The opcode is
eventually replaced with a regular f2f16 in the late optimisations so
the backends don’t need to handle it.
