Operands of an addition will be promoted to int making the a+b<a
kind of checks ineffective.
Use u_overflow.h helpers to perform the check correctly.
The commit would be simpler if it used __typeof__ like so:
util_add_check_overflow(__typeof__(src0), src0, src1)
But typeof only became a standard in C23 so this commit instead extends
nir_opcodes a bit to allow opcodes that need the dest_type to get it.

It defines a couple of helpers to deal with signed and unsigned
integers overflow.
If __builtin_add_overflow (and others) intrinics are available
they're used, otherwise overflow checks are done manually.

This module has existed, unchanged, since Meson 0.64, and is now marked
as API stable in 1.8. It provides a number of helpers that reduce the

blobAlignment helps with running a 4KB guest on a 16KB host.
But for 16KB guest on 4KB host, we'll need to check guest
size too. os_get_page_size(..) might not work on all target

Add support for hardware-accelerated transform feedback using the TFB
command register to control capture state.
Maintains the hardware state through an enum distinguishing between
idle (no hardware state established), active (hardware currently
capturing), and paused (hardware stopped).
Hardware commands are emitted based on state transitions:
- ENABLE when moving from idle to active
- RESUME when transitioning from paused to active
- DISABLE when stopping capture
Transform feedback buffer setup is using the existing dirty state
mechanism through ETNA_DIRTY_STREAMOUT_BUFS, while command emission uses
the new ETNA_DIRTY_STREAMOUT_CMD flag. Buffer descriptors are computed by
mapping vertex shader transform feedback outputs to fragment shader input
registers, as required by the hardware.
A 64-byte context buffer is allocated per context to maintain hardware
state isolation between applications using transform feedback
simultaneously. The hardware state persists across pause and resume
cycles within a command stream but resets during flushes since transform
feedback state does not survive command buffer boundaries.
The implementation enables the full transform feedback capability with
support for 4 buffers and up to 64 separate or interleaved components,
replacing the previous debug-only stub implementation.

Add support for transform feedback primitive counting queries using the
hardware TFB query mechanism. The implementation uses dedicated query
registers (VIVS_TFB_QUERY_BUFFER and VIVS_TFB_QUERY_COMMAND) to track
the number of primitives written during transform feedback operations.
The hardware automatically accumulates primitive counts and stores the
final result at offset 0 of the query buffer, eliminating the need for
manual accumulation.
