[PATCH] Match x86 family machine constraints section with constarints.md

[Peryt, Sebastian]

Hi,

This patch updates x86 family machine constraints section in '16.8.5 
Constraints for Particular Machines' section to match the ones in 
'config/i386/constraints.md'.

gcc/
        * doc/md.texi (Machine Constraints): Update x86 family machine 
constraints
           section to match 'config/i386/constraints.md'.

Is it ok for trunk?

Sebastian
