Emitted IR is byte-identical for every case — proven by the IR-pin
suites (eq_primitives_pin, ord_int_intercept_ir_pin, the raw_buf_*
and drop/leak pins) and the full e2e suite, all green.
intercepts.rs:
- The twelve emit_rawbuf_{new,get,set,size}_{int,float,bool} functions
were copy-paste across three element types, differing only in the
element width (8/8/1) and the LLVM load/store type (i64/double/i1).
Collapsed to four parameterised cores; the element variants are thin
call sites passing the (width, type) pair.
- Replaced the repeated, off-by-one-prone parameter-SSA extraction
idiom (`locals[n-2]`, `locals[n-1]`) with an Emitter::last_param_ssas
helper.
- Factored the shared IR-Str bytes GEP out of emit_eq_str /
emit_compare_str into emit_str_bytes_gep.
drop.rs:
- The three emit_*_drop_fn_for_type methods shared one wrapping shape
(monomorphic short-circuit, else loop over instantiations dispatching
to a *_for_instantiation helper); hoisted into emit_drop_fn_wrapper
taking the per-instantiation emitter as a fn pointer.
- emit_flat_intrinsic_drop_fn / _partial_drop_fn differed only in the
symbol prefix and an ignored mask param; merged into one inner
emitter.
No INTERCEPTS-registry or (intrinsic)-marker changes.
