Changes:
- Add "isl/" as a system library prefix. Even though isl is regularly
imported into polly, it is still used like an external library.
- Add "json/" as a system library prefix. Polly uses json-cpp as external
library.
- Distinguish between llvm and subproject libraries. Always sort subprojects
before LLVM. This was already the case with clang, as 'clang' comes before
'llvm', but we also want 'polly' to be sorted before 'llvm'.
The sorting of headers that are not part of Polly or isl remains unchanged.

"""Script to sort the top-most block of #include lines.

Assumes the LLVM coding conventions.

Currently, this script only bothers sorting the llvm/... headers. Patches

welcome for more functionality, and sorting other header groups.
