Yes; here are the new byte codes in the lexical-binding branch:
#define Bstack_ref 0
#define Bstack_set 0262
#define Bstack_set2 0263
#define Bvec_ref 0264
#define Bvec_set 0265
#define BdiscardN 0266
stack_ref is a `1 byte with embedded constant' opcode; stack_set2 uses a
following 2-byte constant, the rest use a following 1-byte constant (as they
have lisp-level equivalents, unusually large offsets can be handled by
calling an out-of-line function). discardN uses a hack that allows the TOS
to optionally be preserved.
