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.

+%% Program which resulted in a badarg crash when compiled to native code.
+%% The problem was that hipe_icode_primops was stating that the primop
+%% {bs_start_match, ok_matchstate} could not fail which made the icode_type
+%% pass removing the third clause of flatb/1.
+%%
+%% (The program was working correctly with hipe option 'no_icode_type'.)
+%%
+%% Reported by Andreas Sandberg on 3/1/2011 and fixed by Kostis on 5/1/2011
+%% with the help of Per Gustafsson.
