feat(decomp): bank main:func_8006252C (§378 chain + the double re-tie)

Browse Source 
Took three tools in order, and the first two were wrong:
  - scope_demote_drafts BROKE it (it aliased D_80078D08 through __asm__ and the
    build failed) — the clash was never a data extern
  - the real clash was func_8006252C ITSELF: TU void(void) vs draft s32(void),
    i.e. self_decl_tu -> cast_self_callers --sync-decls, 4 call sites
  - then sync_tu_decls closed func_800625DC and func_80062644

The BODY is the interesting part and is now cookbook §482: two INDEPENDENT asm
re-ties, ordered, because one barrier fixes one residual and re-creates the
other.
