[PATCH 3/3] x86: simplify one case of base opcode setting in optimize_encoding()

This patch simplifies a specific case within the optimize_encoding function in the x86 assembler configuration. It removes redundant logic for setting the base opcode, making the code slightly cleaner by directly assigning the known value when certain conditions are met, as the W property is evaluated later.
