Don't generate useless string checks for string adds.

If we know that one side of a string add is definitely a string
(i.e. if it's a string constant), then we don't need to emit a
string check for the argument.

This adds a new BuildCheckString() method to the graph builder,
which does "the right thing".

Removed unused --preallocate-message-memory flag.

It results in a lot of dead code, and Isolate::PrintStack itself
crashes most of the time when something went wrong earlier.
Furthermore, we have plans do get better information into the
minidump, anyway.
