Lifts the Int-only restriction on `==`. Declared type becomes
forall a. Fn(a, a) -> Bool; codegen monomorphises and dispatches:
Int → icmp eq i64
Bool → icmp eq i1
Str → call @strcmp + icmp eq i32 0
Unit → constant true (operands still emitted for side effects)
ADT / Fn / other → CodegenError::Internal
This unblocks 16c's build_eq for non-Int lit patterns. == joins
__unreachable__ as the second polymorphic builtin (same Forall
machinery).
- check/builtins.rs: == registered as Forall(a, Fn(a, a) -> Bool).
- codegen: lower_eq dispatch table; @strcmp declared in IR header
alongside @printf/@GC_malloc/@puts.
- examples/eq_demo.{ailx,ail.json}: covers all four supported
scalars including a Str-lit-pattern match.
- IR snapshots refreshed: only +declare i32 @strcmp(ptr, ptr) in
the header; every define body bit-identical.
- e2e + check + codegen tests: 124 → 133 (+9, of which +1 is the
e2e fixture and the rest exercise the new dispatch / typecheck
surface).
Other comparison ops (<, <=, >, >=, !=) remain Int-only — out of
scope for this iter.
