Change xconst8, xconst16, xconst32 and xconst64 instructions to sign-extend rather than zero-extend their immediates.

Kmeakin commented on PR #9075:

Would you be up for switching the xconst* instructions to sign extending instead of zero extending? I think it probably doesn't makes sense to burn the opcode space on both sign- and zero-extending constant instructions, and sign extending is a little more flexible in general, so I think it would be better to only have sign-extending constant instructions.

Sure
