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.

// Pack-fn (or any comptime-param fn) with a block body containing
|
|
// an explicit `return X;` lowers to clean IR — the inline-return
|
|
// path stores into a dedicated result slot and branches to the
|
|
// shared `ret_done` block instead of emitting a `ret` inside the
|
|
// caller's basic block. Without that, LLVM's verifier rejected the
|
|
// IR with "Terminator found in the middle of a basic block".
|
|
//
|
|
// Surfaced by the variadic heterogeneous type packs feature (step
|
|
// 1 made `..$args` parseable, so the simplest pack-fn smoke test
|
|
// exercised the bug). The root cause is broader than packs: ANY
|
|
// comptime fn with `is_comptime` params, a non-void return, and a
|
|
// block body with `return X;` had the same crash. `format`/`print`
|
|
// use arrow form (`=> expr`) or `#insert`-only bodies, so the bug
|
|
// was invisible until pack-fn bodies surfaced it.
|
|
//
|
|
// Once fixed, calling foo() reaches the body's `return 42;`, the
|
|
// inliner stores 42 into a result slot, the caller loads it as the
|
|
// inline value, and main prints "42".
