Add tests for the HiPE compiler (Part 1: binaries and bitstrings)

Create tests for the HiPE native code compiler. This is the first
part of the effort and contains tests that check that the native
code produced by the HiPE compiler for binaries and bitstrings is
OK and behaves similarly to the code produced by the BEAM compiler.
Add a Makefile for the HiPE tests
Add check so that tests are skipped if HiPE is not available
Up the time limit (globally) for some slow machines
Correct a contract in the igor module

Thanks Kostis.
