Make check-clang depend on the clang-check binary always

check-clang (the target that runs all clang tests) used to
only depend on clang-check (a binary like clang-tidy,
clang-refactor, etc) if the static analyzer is enabled.
However, several lit tests call clang-check unconditionally,
so always depend on it.

Fixes a "could not find clang-check" lit warning in clean builds with
the static analyzer disabled.

Also sort the deps in the CMake file and put just one dep on each line.
