This introduces a conservative prediction for each exception handler
whether it will locally catch an exception or re-throw it to outside
the code bondaries. It will allow for a more intuitive prediction of
whether an exception is considered "caught" or "uncaught".

We need the shared function info of inlined functions to prevent code
flushing for their unoptimized code, and also to make sure that liveedit
can find the proper functions to deoptimize.

The control flow optimization should work independent of the JSGraph. We
used the JSGraph there because it was convinient, not because it was
necessary.

The SimplifiedOperatorReducer is (mostly) unused, except for the very
rough store elimination, and just eats compilation time.

The list of inlined functions is used in exactly two places - for live
edit and to prevent code flushing for inlined functions - and those are
fine with SharedFunctionInfo and don't require a closure.

This is one additional step towards inlining based on SharedFunctionInfo
instead of JSFunction.

Neither the increment nor the comparison can deoptimize, so we don't

Implements the strong mode proposal's restrictions on the ability of user code
to modify the prototype of strong objects.

Setting the strong bit is still wip, so this change will only affect those
objects that have the bit correctly set. The tests reflect this, and will be
expanded as more objects can be marked as strong.

The DCHECK was a lie. The idea was that - when a bookmark is set -
the scanner must clearly be at a character boundary and hence the
bookmark does not need to save a 'partial' UTF-8 code point. The
first part is true - the Scanner is always at a character boundary -
but the 'partial' UTF-8 code point is at the end of a block, not at
the current character position of the Scanner.
Hence, the 'partial' character needs to be saved as well.
