[PATCH] D48866: [clang-tidy] Add incorrect-pointer-cast checker

[Roman Lebedev via Phabricator via cfe-commits]

`Warn for cases when the pointed to type is wider than the allocated type.`
What does that mean? Is this talking about the size of the allocation, or the alignment?

Are you aware of the previous attempts, namely https://reviews.llvm.org/D33826?
Please incorporate the tests from there.

Please add tests with casts (that should normally be diagnosed) from types with explicitly specified alignment, that silence the warning.
