x86-64: adjust stack insn test case

Browse Source 
The value chosen for the 16-/32-bit immediate cases didn't work well
with the subsequent insn's REX prefix - we ought to pick a value the
upper two bytes of which evaluate to a 2-byte insn. Bump the values
accordingly, allowing the subsequent insn to actually have the intended
REX.W.
