Summary:
Little cleanup to lift-out and to remove some frequently used
ast-matchers.
Some of theses matchers are candidates to be lifted to ASTMatchers.h.

Summary:
In Release mode, the check was infinite looping over chromium code base.
It seems there is something strange with the creation of the Maps.
I believe the compiler is making some assumption with the implicit conversion from enum <-> int.
By moving the map to a standard switch/cases, we no longer allocate memory and we can keep the same behavior. For a small amount of elements, this is fine.

Summary:
Existing checker misc-misplaced-widening-cast was extended:
- New use cases: casted expression as lhs or rhs of a logical comparison or function argument
- New types: beside int, long and long long various char types, short and int128 added
- New option to check implicit casts: forgetting a cast is at least as common and as dangerous as misplacing it. This option can be disabled.
This patch depends on AST Matcher patches D17986 and D18243 and also contains fix for checker misc-bool-pointer-implicit-conversion needed because of the fix in the AST Matcher patch.

I added portability warnings when int results are casted to long. I forgot to handle uint, ulong and ulonglong.
Tested on x86 and powerpc targets, hope it works now on all buildbots.
