483749d2 - LookupVisibleDecls: Find generic parameters in methods inside extensions

LookupVisibleDecls: Find generic parameters in methods inside extensions The logic here had diverged from UnqualifiedLookup. One day we'll merge the two, for now clean it up a bit to match. Note that all generic parameters now have 'Reason' reported as 'Local'. I don't believe this really matters. Fixes <rdar://problem/20530021>.
