Further improve lowering constants for binop/lit8 and binop/lit16

  * Don't explicitly number the instructions
  * Cache negative path checks between basic blocks

This brings the compilation time of the supplied repro down to 29s (13s
seconds for d8). These numbers are from a P920, and the user time is
4m40s and 2m40s respectively.

On the supplied repro the d8 size saving is 342 bytes of dex when the
binop/2addr check is included (compressed it actually grown with 1837 bytes)
