[PATCH] D42728: Add more warnings for implict conversions (e.g. double truncation to float).

[Andrew V. Tischenko via Phabricator via llvm-commits]

As it's set in Bug 32048 at the moment Clang misses a lot of warnings about "possibly problematic" conversions. This patch adds such warnings in places where we have different kinds of assignments.
Alexey, could you have look at OpenMP tests - maybe it's better to change something?
