f46906d7a8 Reduce size of LIR instruction by one word and remove dead code. 
Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.

This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.

Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

93113da5a2 Eliminate redundant array bound checks (checks already performed earlier in the DT). 
As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.

cac8bbff6e Replaced the --limit-inling flag by three separate flags and bumped hard limits. 
This change makes experiments with inlining limits much easier. Note that the
default values for the limits keep their old values for now. Renamed things a
bit for more consistency.

3760893edd Fix bug in forced-deletion of globals. 
When inling functions across contexts in optimized code and using
ForceDelete from the API to delete a DontDelete global property we
can end up returning the hole value instead of throwing a ReferenceError
as expected after accessing a deleted global variable.
