// A value-position match (`if subject == { case … }`) returning a small
// integer type works when arms mix positive and negated literals: every arm
// value is lowered against the merge's result type, so the phi operands all
// share one width.
//
// Regression (issue 0066): a negated-literal arm (`else: -1`) previously
// lowered at a narrower width than the positive arms, tripping LLVM's
// "PHI node operands are not the same type as the result".
