Hoping to change the maxskip setting from 10 to 12 (-march=haswell), I
set -falign-loops=12 and found that the maxskip value is removed from .s
output.
I see that max_skip is initialized in i386.c (for the case where
-falign-loops is not set) but thought there might be a compile-time option.

I rebuilt gcc after changing the align_loop_max_skip field to 12 in config/i386/i386.c but it had no effect.
