Improve byte-switch execution.

* lisp/emacs-lisp/byte-opt.el,
  lisp/emacs-lisp/bytecomp.el (byte-decompile-bytecode-1),
  (byte-compile-lapcode): Calculate the actual jump address while
  compiling, store it in the jump table.

* src/bytecode.c: Jump to the looked up value directly, do a linear
  search when the number of elements is <= 5.
