Between this and the previous few commits, the Box<> has moved from
outside of Instr to inside the Op enum. This provides a few benefits:
1. We no longer need to allocate for the worst-case Op on every
instruction. For example, OpIAdd3X is 232 bytes and OpBra is 40
bytes, which means we can save some memory on OpBra if we only
allocate those 40 bytes.
2. The Op discriminant is available without chasing a pointer. The type
of op is probably the most frequently used field, and this should
benefit most passes that care about what type of Op they're
handling.
3. Small Ops don't need any indirection at all. For example, OpPBk is
only 4 bytes, which means we can just store it directly in less
space than a pointer.
Compared to Box<Instr>, this is around a 1.4% shader compile time
improvement.

When recreating aux_context (typically following a GPU reset event),
the u_log_context must be properly initialized based on the aux_debug
enablement state, just like the logic in the function
radeonsi_screen_create_impl() during aux_context creation. Otherwise,
wrong u_log_context setting will lead to Mesa crashes. For example, in
si_blit_decompress_color(), it will check sctx->log to decide whether
to call u_log_printf(), which ultimately causes a crash.

Move from a single ralloc allocation per instruction to contiguous
blocks of allocations. Still use ralloc for those large blocks.
Each ralloc allocation has at least 5 pointers of overhead, which would
be about a third of the current brw_inst, and get worse as we try to
pack brw_inst better.

Move all the SEND specific fields from brw_inst into brw_send_inst.
This new instruction kind will contain all variants of SENDs plus the
virtual opcodes that were already relying on those SEND fields.
Use the `as_send()` helper to go from a brw_inst into the brw_send_inst
when applicable. Some of the code was changed to use the brw_send_inst
type directly.
Until other kinds are added, all the instructions are allocated the same
amount of space as brw_send_inst. This ensures that all
brw_transform_inst() calls are still valid. This will change after
a few patches so that BASE instructions can use less memory.

Prepare code for supporting subclasses of brw_inst for certain
specialized kinds of instructions. This will allow
- Move certain fields from brw_inst to the specialized one,
reducing its size and making it easy to understand what applies
to which instruction;
- Move certain control sources into the specialized inst type, which
currently take a full brw_reg to encode small integers. Reducing
the overall sources we walk and care also might help the code
in general.
Next commits will add the new instruction kinds.

Flatten all the work being done into brw_new_inst() and
brw_clone_inst() and allocate both the instruction and
the sources in one swoop.
For now we still keep a pointer to the array instead of
declaring an array as last element to still allow growing
the array -- which is used by the compiler in a few places.
This commit removes the constructors for brw_inst, the idea
is that the instructions are managed by the brw_shader, so
we always go through it for new ones.

In the few cases we have to _increase_ the number of sources, the new
code will not attempt to recollect the memory, i.e. it delays freeing

happen more than once.

These dependency hints were primarily useful for the vec4 backend, where
it was common to write subsets of a vec4's components across multiple
instructions. In the scalar backend, we rarely used them. They also no
longer exist on Tigerlake and later in favor of software scoreboarding.
Dropping this allows us to clean up the IR a bit.
We still use the hardware hints in the generator in a couple places:
- Gfx9-12.0 scratch headers
- Quad swizzles
- Indirect MOV lowering
In theory we might want them back if we moved that lowering to the IR.
For scratch at least, I suspect it won't have a huge impact, as we're
already incurring the cost of spills/fills. The others are fairly rare
as well, so it may not be worth keeping.
