Attached patch expr-lookahead.patch (obsolete) — Splinter Review
+++ This bug was initially created as a clone of Bug #1286816 +++

The patches that implement boolean optimization for control in the baseline compiler (bug 1286816) will want to examine the next token in the token stream when processing a comparison opcode, to see if the boolean value will be consumed immediately.
Implements an infallible peekOp() that can be used whereever readOp() is legal.  I will need this to implement the optimization in bug 1286816 without adding overhead to the baseline compiler's decoding loop.
