This will spill out information about LLVM-internals. However, in cases
where the name of the Value matches the name of the array in the source,
we provide more useful information. In cases where we spill internals,
the information still might help the user to pin down the correct
arrays.
The problem we face here is: The error is pinned to the debug location
of one of the offending values out of the alias set instead of all of them.
The more information we give the user about the set of aliasing
pointers the better.

Add support for generating optimization remarks after completing the
detection of Scops.
The goal is to provide end-users with useful hints about opportunities that
help to increase the size of the detected Scops in their code.
By default the remark is unspecified and the debug location is empty. Future
patches have to expand on the messages generated.
This patch brings a simple test case for ReportFuncCall to demonstrate the
feature.
Reports all missed opportunities to increase the size/number of valid
Scops:
clang <...> -Rpass-missed="polly-detect" <...>
opt <...> -pass-remarks-missed="polly-detect" <...>
Reports beginning and end of all valid Scops:
clang <...> -Rpass="polly-detect" <...>
opt <...> -pass-remarks="polly-detect" <...>
