Description

Reapply: Use GVN for length loads from arrays and strings. - Fix bug in variable allocation. - Treat all HCheck instructions the same when it comes to GVN. They do not have side-effects. Changes since last version: - give HTypeConversion a typeCode and implement typeEquals and dataEquals. - clear side effects for array and string loads when enabling GVN.
