Migrate the DECLS of the 7 identity-#foreign feature tests to extern/export
(1205-global/-helper, 1207, 1218-cvariadic, 1219, 1306, 1318): fn/global markers →
extern, the 2 objc import classes (1306/1318) → postfix '#objc_class("X") extern {'.
Behavior-preserving (A→B gate + existing extern twins guarantee identical output);
empty snapshot diff, corpus-validated. Comment-only #foreign in these files is left
for the Phase 9.3 doc/comment purge (comments aren't parsed → not cutover-critical).
Suite green (647 corpus / 444 unit, 0 failed).

// `xx @<foreign_global>` round-trips through a non-main helper
|
|
// function: the helper's `xx @__stdinp` cast lowers to a `bitcast`
|
|
// IR opcode that emit_llvm.zig dispatches to `LLVMBuildPtrToInt`
|
|
// (BitCast doesn't accept ptr↔int on modern LLVM with opaque
|
|
// pointers), and a `u64`-returning function correctly returns
|
|
// the address.
|
|
//
|
|
// Was issue-0037 — the helper used to emit `ret i64 undef` because
|
|
// `coerceToType` had no pointer↔integer case, so the explicit
|
|
// `xx ptr` cast produced an unchanged pointer value handed to a
|
|
// `ret i64` slot.
