[flang][NFC] Restrict -funroll-loops tests to known working targets

[DavidTruby]

If -funroll-loops tests are not restricted to specific targets the tests may behave differently based on the host platform. This patch restricts the tests to aarch64 and x86_64, and removes the PowerPC XFAIL.

@mustartt I've tried again to fix the ppc failures here. I think it should work this time, as well as resolving the sparc failure reported by @rorth

If -funroll-loops tests are not restricted to specific targets the tests may behave differently based on the host platform. This patch restricts the tests to aarch64 and x86_64, and removes the PowerPC XFAIL.

[mustartt]

Thank you for updating the test case. We don't have non PPC target enabled in the buildbut. I will add our PPC expected test case soon.

[tblah]

Thanks

[DavidSpickett]

Might want to keep the PPC issue links but otherwise LGTM.

[DavidSpickett]

Sounds like this issue may get fixed very soon, but I would still leave the link in here just in case that does not happen.

[DavidSpickett]

It seems like every day I learn a new lit feature.
