Yes, but the difference is negligible.  In FSharp the number of RGCTXs
that need to be creates goes down to 647 (from 651).  On the other
hand, more RGCTXs (most of which are of course never needed) are
allocated when code is inlined (i.e. more classes/vtables which
require RGCTXs are initialized).  I'm not quite sure why that is,
though.  It wouldn't be an issue when we do RGCTX allocation lazily

I should also mention that we currently don't allow inlining in shared
code, for the simple reason that it's not implemented yet.
