This patchlet fixes length computation of "std %0,%1" and "st %0,%1" that reported 2 instead of 1. The reason is that the insn length was accumulated and added to the length of 1 already set in the caller.
These length are unconditionally set to 1 now because there is no code emit before these instructions and there is no need to accumulate lengths.
