Since the binding value can be any 32-bit number, we cannot assume that
it is <= 27 bits. We need 64-bit keys to accommodate a 32-bit binding.
This will also provide more bits to store the subdesc id, which will be
needed for multiplane texture and sampler descriptors.

We're about to start lowering these in the IR, at which point the
scheduler will see SEND instructions with fence messages. Previously,
we handled those in the generator, and didn't handle the virtual opcodes
here, letting them fall through to the default case of 14 cycles.
These new numbers are completely fabricated, matching the times we have
for atomic operations. This is basically what we did for LSC atomics.
While it may not be accurate, it's at least better than 14 cycles.

Memory fences do not refer to an element of a binding table. Rather,
the reason we had "BTI" in these opcodes was to distinguish what in
modern terms are called UGM (untyped memory data cache) vs. SLM
(cross-thread shared local memory) fences.
Icelake and older platforms used the "data cache" SFID for both
purposes, distinguishing them by having a special binding table
index, 254, meaning "this is actually SLM access". This is where
the notion that fences had BTIs came in. (In fact, prior to Icelake,
separate SLM fences were not a thing, so BTI wasn't used there either.)
To avoid confusion about BTI being involved, we choose a simpler lie: we
have Icelake SLM fences target GFX12_SFID_SLM (like modern platforms
would), even though it didn't really exist back then. Later lowering
code sets it back to the correct Data Cache SFID with magic SLM binding
table index. This eliminates BTI everywhere and an unnecessary source.

For some reason, we were using UW type for the destination of memory
fences at the generator level, while in the IR we selected UD.
There are some comments in the documentation for the message about it
writing the notification register to the destination, which is 32-bit.
Prior to Xe2, bits 31:16 were Reserved/MBZ. But on Xe2, all 32 bits
are populated with actual data.
I don't know whether this will fix anything in practice, but it seems
like a better plan to use UD. Often we used UW types to avoid having
the destination region of sends span too many registers, but we're in
SIMD1 here, so it shouldn't matter.

brw_memory_fence() overrides the instructions generated by the
MEMORY_FENCE or INTERLOCK opcodes to be force_writemask_all with
exec_size == 1. But the IR was emitting it in SIMD8 (regardless
of dispatch width). Instead, just emit the IR as SIMD1/NoMask so
the IR matches what we actually generate. Have size_written indicate
that the entire destination is written, however, as it is ultimately
going to be a SEND that writes a whole register.
We were also using a UD register for the source of
FS_OPCODE_SCHEDULING_FENCE when the generator overrides it to UW,
so just specify UW in the IR as well so that they line up.
Also add validation for MEMORY_FENCE/INTERLOCK that we've done the
exec_size and masking right in the IR.

simply set a source on our logical FB write messages. (We already do
so for many other cases.)
In the repclear shader, setting this wasn't actually having an effect,
as we were setting it on a SHADER_OPCODE_SEND message which ignored it.
