I measured the performance for mcs.exe build and put the results
here:

Without managed collation:

Time(ms) Count   P/call(ms) Method name
########################
 42615.000   10244    4.160   Mono.CSharp.Block::Resolve(EmitContext)
Total memory allocated: 54744 KB

With managed collation:

Time(ms) Count   P/call(ms) Method name
########################
 46646.000   10244    4.553   Mono.CSharp.Block::Resolve(EmitContext)
Total memory allocated: 54926 KB

So it was not that big, _only_ 200KB, while I thought it was bigger.
It also tells that the performance is so bad (well, it is not fair
comparison since no collation comparison is much faster).
