While compiling current HEAD on a ppc64 box, I was confronted with the
following compile errors:

  tcg/optimize.c: In function ‘tcg_constant_folding’:
  tcg/optimize.c:546: error: ‘INDEX_op_not_i32’ undeclared (first use in this function)
  tcg/optimize.c:546: error: (Each undeclared identifier is reported only once
  tcg/optimize.c:546: error: for each function it appears in.)
  tcg/optimize.c:546: error: ‘INDEX_op_not_i64’ undeclared (first use in this function)
  tcg/optimize.c:573: error: ‘INDEX_op_ext32u_i64’ undeclared (first use in this function)
  make[1]: *** [tcg/optimize.o] Error 1

Obviously, the optimize.c tries to use TCG opcode constants that are optional
and thus not defined in some targets, such as ppc64.

This patch guards them with the proper #ifdefs, so compilation works again.
