What I did

  • use SHL/SHR for bitshifting when targeting >=constantinople EVM ruleset - closes #1268
  • bitshift bytecode optimizations

How I did it

functions.functions.shift: When _shift is a literal, do not include IF SLT 0 or resulting unreachable bytecode.

How to verify it

Run the tests. I added some new test cases and parametrized existing ones.
