[PATCH] Mark param_min_crossjump_insns with Optimization keyword.

[Martin Liška]

Hi.

Again, the param is set based on optimize_size:

  if (opts->x_optimize_size)
    /* We want to crossjump as much as possible.  */
    SET_OPTION_IF_UNSET (opts, opts_set, param_min_crossjump_insns, 1);

So that, the param should be per-function. The only usage is in cfgcleanup
that is done per-function.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
