Instantiate a ClangTidyDiagnosticConsumer also for the plugin case and
let it forward the diagnostics to the external diagnostic engine that is
already in place.
One minor difference to the clang-tidy executable case is that the
compiler checks/diagnostics are referred to with their original name.
For example, for -Wunused-variable the plugin will refer to the check as
"-Wunused-variable" while the clang-tidy executable will refer to that
as "clang-diagnostic- unused-variable". This is because the compiler
diagnostics never reach ClangTidyDiagnosticConsumer.

Summary:
Previously, we intended to omit the check fix to the case when constructor has
any braced-init-list argument. But the HasListInitializedArgument was not
correct to handle all cases (Foo(Bar{1, 2}) will return false in C++14
mode).
This patch fixes it, corrects the tests, and makes the check to run at C++17 mode.

Revise the google-objc-global-variable-declaration check to match the style guide.
This commit updates the check as follows:
(1) Do not emit fixes for extern global constants.
(2) Allow the second character of prefixes for constants to be numeric (the new guideline is that global constants should generally be named with a prefix that begins with a capital letter followed by one or more capital letters or numbers).

This patch adjusts `PragmaOpenMPHandler` to set the location of
`tok::annot_pragma_openmp` to the `#pragma` location instead of the
`omp` location so that the former becomes the start location of the
OpenMP AST node. This can be useful when, for example, rewriting a
directive using Clang's Rewrite facility. Most of this patch updates
tests for changes to locations in diagnostics and `-ast-dump` output.

Thanks to Don Hinton for advice.
As well, this change adds a note for this check's applicability to code
targeting OpenMP prior version 5 as this check will continue breaking
compilation with `-fopenmp`. Thanks to Roman Lebedev for pointing this
out.

Summary:
This check searches for copy assignment operators which might not handle self-assignment properly. There are three patterns of
handling a self assignment situation: self check, copy-and-swap or the less common copy-and-move. The new check warns if none of
these patterns is found in a user defined implementation.

Some programmers tend to forget that subtracting two pointers results in the
difference between them in number of elements of the pointee type instead of
bytes. This leads to codes such as `size_t size = (p - q) / sizeof(int)` where
`p` and `q` are of type `int*`. Or similarily, `if (p - q < buffer_size *
sizeof(int)) { ... }`. This patch extends `bugprone-sizeof-expression` to
detect such cases.
