HiPE has had metadata for gc safety on it's temporaries for a while, but
it has never been enforced or even checked, so naturally several
gc-safety violations has slipped through.
A new pass, hipe_rtl_verify_gcsafe verifies gcsafety on optimised RTL
and is used when running the testsuite, and can be manually enabled with
+{hipe,[verify_gcsafe]}.

Now that x86 is no longer broken with these optimisation levels, we add
them to the test suite to ensure they do not break again.
Bump timeout to 6min since tests are run twice as many times.
The option set of o1 was changed to all optimisations that run fast on
both big and small programs, incurring only a slight compile time
increase compared to the old set, but with a, presumably, significant
improvement to speed of compiled code.
Change o0 register allocator to linear_scan.

* margnus1/hipe/maps-is_key-opts/PR-1069/OTP-13625:
hipe: Add test suite for verifying optimisations
Added elimination of maps:is_key/2 calls to HiPE
|
|
* Added a suite opt_verify_SUITE.erl to HiPE that tests for the results
of optimisations, with a single testcase that checks that the
icode_call_elim optimisation pass does remove calls to maps:is_key/2
where sound and not otherwise.
* Made hipe_testsuite_driver only create explicitly listed suites.

Without this change, one test (bs_utf) times out when run on some
very slow SUN/SPARC machine we still have around. Unfortunately,
this is the only such machine that we have access to these days.
Perhaps suprisingly, all the HiPE tests pass on SPARC, which is
nice to know that this backend still works, despite not having
been tested for more than one (almost two?) years now.

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.
