patch to add -mlra option

I'd like to apply the patch to add a transitional option -mlra
like ARM and the revised patches in c#78 and c#83 on sh-lra branch
after merge from trunk.  It helps me a lot when building, comparing
and testing sh-lra compilers.

Sure, makes sense to me.  It's probably better to revert my commit r215244 to
reinstate reload on the sh-lra branch.
