Merging r195339:

r195339 | chapuni | 2013-11-21 02:55:15 -0800 (Thu, 21 Nov 2013) | 5 lines

Revert r195317 (and r195333), "Teach ISel not to optimize 'optnone' functions."

It broke, at least, i686 target. It is reproducible with "llc -mtriple=i686-unknown".

FYI, it didn't appear to add either "-O0" or "-fast-isel".
