  2. Implement new optimization pass to turn ?mul to ?shl 

    This commit introduces new optimization pass - `TRILXmul2Xshl` - which
replaces

    ?mul
      <value>
      ?const <power of two>

with

    ?shl
      <value>
      ?const <log2 of <power of two>>

While this may not have real impact on modern CPUs, it serves as an
example of how to do simple TRIL-to-TRIL optimizations.

It is *not* included in default optimization pipeline as of now (and
may never be).

  5. Silence errors (in fact, warnings) when shadowing a variable in tests 

    This commit silence errors produced by Pharo compiler about variables
being shadowed. The way Pharo browser is handling it makes it impossible
to ignore the warning (one cannot accept). Sigh.
