This change introduces five fused bytecodes for common bytecode sequences on popular websites. These are LdrNamedProperty, LdrKeyedProperty, LdrGlobal, LdrContextSlot, and LdrUndefined. These load values into a destination register operand instead of the accumulator. They are emitted by the peephole optimizer.
