[Fortran/gfortran] Enable tests that now pass

[tarunprabhu]

This is likely to be dependent on another PR.

@jeanPerier attempted to enable several of these tests once before, but there were issues with the not utility in the test suite that prevented the tests from being enabled then. The first PR linked above should have fixed those, so once that lands, these tests should also work.

Thanks for the update. All passes for me now

@tblah, @AlexisPerry,

#142 was just merged. Do you mind checking this again now? Perhaps I'm being a bit overcautious. Thanks!

[tblah]

Still works for me

Hi @tarunprabhu, @tblah, @jeanPerier,
It looks like some of our bots are broken since this commit:
clang-aarch64-full-2stage https://lab.llvm.org/buildbot/#/builders/84/builds/480
clang-aarch64-sve-vla-2stage https://lab.llvm.org/buildbot/#/builders/41/builds/903
clang-aarch64-sve-vls-2stage https://lab.llvm.org/buildbot/#/builders/4/builds/937
clang-aarch64-sve-vla https://lab.llvm.org/buildbot/#/builders/17/builds/1349
clang-aarch64-sve-vls https://lab.llvm.org/buildbot/#/builders/143/builds/917
I still dont understand why all these NOEXE errors, but it seems that at least internal_dummy_2.f08 cannot be re-enabled.
Could you please look at this ?

[tarunprabhu]

I'm taking a look now.

The NOEXE errors don't seem to be coming from the fortran tests, so I can't really speak to those. I could not replicate the error on the AArch64 machine to which I have access.

Based on an exchange with @tblah and @kiranchandramohan, the failure may occur if compiler-rt is not available. Is this the case with these build bots?
