patch for targetm.override_options_after_change

Could you try this patch?

What is going on:

1. align_jumps (global_options.x_align_jumps) is set to 1 as the default value.
2. sh_override_option changes it to 2.
3. pragma handling saves it and sets it back to the default value 1.
4. compile function where align_jumps is 1.
   This results a bad code with wrong alignments.
5. Restore align_jumps at the end of compilation of this unit.

I've noticed that other targets define TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE
and avoid this issue of pragma for optimization.  See aarch64 or alpha's
*_override_options_after_change for example.
