42a2b4ede7 Improve fast to slow elements conversion:
o Use a more strict limit for old arrays.

o Initial capacity of a slow elements dictionary should be the number
  of used elements and not the old array capacity.

73f8cec70e Do not explicitly record undetectable objects in the ToBoolean stub.
Loading the map within the stub already implies a check for an undetectable
object, so there is no need to record this separately. Furthermore, this brings
the size of the type info to record down to 8 bits, removing the need to find a
place for the ninth bit in the Code object. ;-)

f7138b1427 Implement a type recording ToBoolean IC.
The IC records the set of types it has seen, e.g. {String} or {Boolean,
Undefined}, etc.  Note that in theory this could lead to a large number of
different ToBoolean ICs (512, to be exact, because we distinguish 9 types),
but in practice only a small handful of them are actually generated.

Currently the type recording part is only implemented on ia32, other platforms
continue to work like they did before, though.

Removed some dead code on the way.
