If you didn't have a freed+ready instruction, you'd redo the live_effect
and check_instr() logic multiple times per instr. Replace the multiple
loops in each function with a ranking that I think is more readable,
reducing the overhead in the process.

Originally I fixed the case where the nir itself has a shared mem size of
0, but the frontend (e.g. clover) set it to some other value.
But st/mesa sets the shared mem size on the state object as well and we
end up actually doubling the value in the driver as we set smemSize to the
value from the state object before calling into the compiler.
So just max the value instead.
Fixes the compute_shader.shared-max CTS test.

We only actually use 4-bits, so we could shrink again. But this by
itself means 1/2 the memory usage for liveness analysis and 1/2 the

Since p_elect doesn't have any operands, ACO's value numbering and/or
the pre-RA optimizer could currently recognize two p_elect instructions
in two different blocks as the same.
This patch adds exec as an operand to p_elect in order to achieve
correct behavior.

This replaces some new/delete uses with malloc/free.
This is more consistent with most of the other glsl IR code but
more importantly it allows the game "Battle Block Theater" to
start working on some mesa drivers. The game overrides new and
ends up throwing an assert and crashing when it sees this
function calling new [0].
Note: The game still crashes with radeonsi due to similar conflicts
with LLVM.

Also the read_only flag is for consts, shader inputs, and uniforms. The

The only reason we had to refcount semaphores was for the ancient
sync_file semaphores which we used for pre-syncobj kernels. Now that we
assume syncobj and that code is gone, we don't need reference counting
anymore either.

Sync object for i915 support has been in upstream Linux since 4.14 which
is 3.5 years old at this point and, as far as we can tell, it also
exists in all the ChromeOS kernels. Assuming it allows us to drop some
of our more gnarly synchronization fall-back paths.
At the time of merge, ChromeOS was on the following kernels:
- kernel 3.18: SKL
- kernel 4.4: BYT, KBL, APL
- Kernel 4.14: BDW, GLK
All of the pre-4.14 kernels have had syncobj support back-ported.
