Arcanist (arc) will now always run linters before uploading any new
commit to Phabricator. All errors/warnings (or their absence) will be
shown in the web interface together with a explanation by the commiter
(arcanist will ask the commiter if the build was not clean).
The linters include:
- clang-format
- spelling check
- permissions check (aka. chmod)
- filename check
- merge conflict marker check
Note, that their scope is sometimes limited (see .arclint for
details).
This commit also fixes all errors and warnings these linters reported,
namely:
- spelling mistakes and typos
- executable permissions for various text files

During code preperation trivial PHI nodes (mainly introduced by lcssa) are
deleted to decrease the number of introduced allocas (==> dependences). However
simply replacing them by their only incoming value would cause the independent
block pass to introduce new allocas. To prevent this we try to share stack slots
during code preperarion, hence to reuse a already created alloca 'to demote' the
trivial PHI node. This works if we know that the value stored in this alloca
will be the incoming value of the trivial PHI at the end of the predecessor
block of this trivial PHI.
