Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.

// Phase 1 step 1.4 (PLAN-FFI.md): multiple `#objc_call` sites
|
|
// with the same selector. Today (after 1.3) each site emits its
|
|
// own `call @sel_registerName(<"init">)`; the actual SEL handle
|
|
// is recomputed per call.
|
|
//
|
|
// 1.5 lands selector interning: one static `SEL` global per
|
|
// unique selector string (named `OBJC_SELECTOR_REFERENCES_init`,
|
|
// matching clang's convention) populated once via the runtime
|
|
// at module init. Per call site becomes a single load.
|
|
//
|
|
// Runtime behavior is unchanged before vs. after 1.5; the
|
|
// improvement is visible in `sx ir` only. The IR snapshot at
|
|
// `tests/expected/ffi-objc-call-03-selector-sharing.ir` locks
|
|
// in today's shape (4 `call ptr @sel_registerName` instructions,
|
|
// one per call site). After 1.5 lands selector interning, the
|
|
// snapshot updates to ≤2 (one per unique selector string) plus
|
|
// a static `@OBJC_SELECTOR_REFERENCES_<sel>` global and loads at
|
|
// the call sites.
