RFR: 8309543: Micro-optimize x86 assembler UseCondCardMark

Tue Jun 6 14:32:05 UTC 2023

Noticed this while explaining a related code: there is no need to make a full jump, and a short jump would suffice. Assembler does not know about this shortening, because it is a forward branch.

Makes a slightly more compact interpreter code.
