Reviewers: Lasse Reichstein,
Description:
Improve the success rate for inline keyed store on x64
Added a simple new space check on the elements fixed array which can allow
updating with other values than smis without updating the remembered set.
Also combined the positive smi and range check so that a separate smi check
can
be avoided when the key is known to be a smi.
This is a port of r4543.
