- Add SSA HArrayFlags{Check,Get,Set} instructions to check for
fixed-length and unmodifiable JSArray and JavaScript typed data
instances.
- Add optimizations to remove redundant checks.
- Added HOutputConstrained interface for instructions that must have
the input and output in the same JavaScript variable. This
generalizes some code generation logic already applied to HCheck.
