            aesni-x86_64.S

Log Message:
Get rid of the "rep ret" trick in places where it is not needed. FWIW,
the "rep ret" trick is recommended by AMD as a branch prediction
optimization in certain circumstances (quoting their manual):

- any kind of branch (either conditional or unconditional) that has the
single-byte near-return RET instruction as its target

- a conditional branch that occurs in the code directly before the
single-byte near-return RET instruction.
