A uint16 value that is widened to int/uint32/uint64 must be zero-extended
(movzwl), and an int16 value must be sign-extended (movswl). coerce_to_type
picks the direction from the source AST node's declared signedness, which
requires the translator; several call sites omitted it and therefore fell
back to sext, so a big-endian uint16 such as 0xDCBC became 0xFFFF...DCBC
(numGlyphs 56508 read as -9028 and every glyph range collapsed to zero).
- pass trans at the assignment, annotated-assignment, augmented-assignment,
global-array initializer, index, element-store, constructor-argument,
conditional-expression and return coercion sites
- printf argument promotion now receives the argument expression and trans,
so uint16/uint8 promote with zext like any other widening
- print selects the format token and extension from the source signedness
(%u/%llu + zext for unsigned, %d/%lld + sext for signed) instead of a
hardcoded %d + sext for 8/16-bit values
