This does not preserve the operand's type as required by `DW_OP_plus_uconst`:
passing `false` changes every narrow signed operand to unsigned, and a signed
64-bit operand is also promoted to unsigned by `operator+=` but skips this
truncation entirely. That affects later signed operations and typed-operand
checks.
