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.

// Variadic heterogeneous type packs — step 2b: per-call-shape
|
|
// monomorphisation. Each unique call signature gets ONE mono fn;
|
|
// repeat calls with the same signature share it. The runtime output
|
|
// confirms correct semantics; the IR (visible via `sx ir`) shows
|
|
// the distinct mono symbols:
|
|
//
|
|
// call @count__pack(ctx)
|
|
// call @count__pack_i64(ctx, 1)
|
|
// call @count__pack_i64(ctx, 2) ← shares with the 1-arg i64 call
|
|
// call @count__pack_i64_i64_i64(ctx, 1, 2, 3)
|
|
// call @count__pack_string_bool(ctx, ..)
|
|
//
|
|
// Before step 2b, each call inlined a fresh copy of the body into
|
|
// main's basic block — no shared symbols, IR size grew linearly in
|
|
// call sites. After 2b, distinct shapes get distinct functions,
|
|
// repeats share, IR scales with unique shapes.
