Konstantin Belousov 8bd1142b52 Perform amd64-specific microoptimizations for native syscall entry 
sequence. The effect is ~1% on the microbenchmark.

In particular, do not restore registers which are preserved by the
C calling sequence. Align the jump target. Avoid unneeded memory
accesses by calculating some data in syscall entry trampoline.
