Built on the number-output words and executed on the golden model at
both cell widths against a C reference and recorded transcripts of the
v3 binary (DUMP byte for byte at 64-bit cells).
Q.PRINT is signed (D-8) and always decimal; DUMP is always hex; both
put BASE back. Each keeps its working state in a variable, (QP) and
(DP), so each leaves its caller 4 data cells and 2 return entries.
