Summary:
The cppcoreguidelines-pro-bounds-pointer-arithmetic warns on all occassion where
pointer arithmetic is used, but does not check values where the pointer types
is deduced via `auto`. This patch adjusts this behaviour and solved
PR36489.
I accidentally commited a wrong patch, this Differential is meant to have a
correct revision description and code attached to it.
Because the patch was accepted by aaron.ballman already, i will just commit
it.
See https://reviews.llvm.org/D48717 for the old differntial (contains wrong
code from the mixup)

Summary:
The goal of the patch is to bring checkers in their appropriate namespace.
This path doesn't change any behavior.

Summary:
This check flags all usage of pointer arithmetic, because it could lead
to an
invalid pointer.
Subtraction of two pointers is not flagged by this check.
Pointers should only refer to single objects, and pointer arithmetic is
fragile and easy to get wrong. array_view is a bounds-checked, safe type
for accessing arrays of data.
This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds1-dont-use-pointer-arithmetic-use-array_view-instead
