vasilito cb424d7448 build: static patch-sanity linter (shift-left the malformed-patch class)

verify-patch-sanity.py validates every active recipe .patch has internally-
consistent hunk line counts — catching the 'malformed patch at line N' failure
at commit/CI/preflight time instead of hours into a cook. This cycle hit that
class three times (qtwaylandscanner, sddm, xwayland), each only discovered when
cookbook tried to apply the patch.

Running it across the repo found 29 latent malformed patches (validated against
GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22').
They were harmless only because they sit in vendored recipes (baked, not re-
applied) — but would fail on any version-bump re-derivation. --fix recounts the
hunk headers (body untouched) and repaired all 29.

Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test
(test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats
(empty placeholders, bare-@@ git hunks).

Builtin Dialect

The builtin dialect contains a core set of Attributes, Operations, and Types that have wide applicability across a very large number of domains and abstractions. Many of the components of this dialect are also instrumental in the implementation of the core IR. As such, this dialect is implicitly loaded in every MLIRContext, and available directly to all users of MLIR.

Given the far-reaching nature of this dialect and the fact that MLIR is extensible by design, any potential additions are heavily scrutinized.

Attributes

Location Attributes

A subset of the builtin attribute values correspond to source locations, that may be attached to Operations.

DistinctAttribute

A DistinctAttribute associates an attribute with a unique identifier. As a result, multiple DistinctAttribute instances may point to the same attribute. Every call to the create function allocates a new DistinctAttribute instance. The address of the attribute instance serves as a temporary unique identifier. Similar to the names of SSA values, the final unique identifiers are generated during pretty printing. This delayed numbering ensures the printed identifiers are deterministic even if multiple DistinctAttribute instances are created in-parallel.

Syntax:

distinct-id ::= integer-literal
distinct-attribute ::= `distinct` `[` distinct-id `]<` attribute `>`

Examples:

#distinct = distinct[0]<42.0 : f32>
#distinct1 = distinct[1]<42.0 : f32>
#distinct2 = distinct[2]<array<i32: 10, 42>>

This mechanism is meant to generate attributes with a unique identifier, which can be used to mark groups of operations that share a common property. For example, groups of aliasing memory operations may be marked using one DistinctAttribute instance per alias group.
