a1d5e8bfdb compiler/rust: Fix the DFS loop detection algorithm
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
The previous algorithm just looked at the dominator's loop header.
However, if you have multiple consecutive loops like:

    function_impl {
        loop {
            // Stuff
        }
        loop {
            // Other stuff
        }
    }

then it will look like the second loop is contained in the first loop
because the first loop's header dominates the second loop.  This isn't
actually what we want.  Instead, we want a node N to be considered part
of a loop with header H if H dominates N and H is reachable from N.

81dd60df95 nir/opt_load_skip_helpers: move divergence check earlier 
This should fix a hypothetical issue such as:
   address = load_global()
   value = load_global(address, access=uses-smem)
where divergence analysis can't prove that 'address' is uniform, but can
prove that 'value' is uniform.

We might then add both load_global to the load_worklist, but only disable
helpers for the first because the second is uniform, making 'address'
divergent for real and potentially incorrect when used with
v_readfirstlane_b32.

ca989ecdec glsl: disable UBSan vptr check for ir_instruction
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
With UBSan enabled, we get the following issue:

```
../src/compiler/glsl/ir.h:116:4: runtime error: member access within address 0x555637c62c10 which does not point to an object of type 'ir_instruction'
0x555637c62c10: note: object has invalid vptr
 5f 76 61 6c  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  00 00 00 00
              ^~~~~~~~~~~~~~~~~~~~~~~
              invalid vptr
```

This only happens the first time a ir_variable (which derives from
ir_instruction) is created; next calls don't show the issue any more.

The problem is with the following call in the `new()` operator:

```
((ir_instruction*)((uintptr_t)p))->node_linalloc = ctx;
```

In this case, the ir_instruction structure is not fully constructed and
thus UBSan complains about it. In the next calls, as the structure is
now fully constructed it doesn't complain any more.

The right approach would be fully creating the structure, and afterwards
doing the context assignment. But this would require quite a lot of
changes, passing the context through the constructors to assign it.

A simpler solution is just disabling this check for this case, as we
know what is happening.

390631e30a nir/opt_dead_write_vars: don't use ralloc context, share dynarray among blocks 
Instead of allocating the ralloc context, which is useless because it's
only used by the dynarray, we can free the dynarray directly.

Also share the same dynarray among all blocks instead of allocating
a new one for every block. This eliminates realloc invocations.
