Fix obvious formatting problems.

We fix the following formatting problems found by clang-format:

  - 80 cols violations
  - Obvious problems with missing or too many spaces
  - multiple new lines in a row

clang-format suggests many more changes, most of them falling in the following
two categories:

  1) clang-format does not at all format a piece of code nicely

  2) The style that clang-format suggests does not match the style used in
     Polly/LLVM

I consider differences caused by reason 1) bugs, which should be fixed by
improving clang-format. Differences due to 2) need to be investigated closer
to understand the cause of the difference and the solution that should be taken.
