This commit ensures that the importing of LLVM modules first verifies
that the module is even valid. As many tests did not work with valid
LLVM IR, they were fixed as part of this commit.
Some error messages were only reachable with invalid input IR, thus they
were replaced with a failures.

This commit moves the importing logic of access group metadata into the
loop annotation importer. These two metadata imports can be grouped
because access groups are only used in combination with
`llvm.loop.parallel_accesses`.
As a nice side effect, this commit decouples the LoopAnnotationImporter
from the ModuleImport class.
