The google-objc-avoid-throwing-exception check enforces the Google
Objective-C Style Guide's prohibition on throwing exceptions in user
code but the check incorrectly triggers findings for code emitted from
system headers. This commit suppresses any findings that do not have
valid locations or are emitted from macros in system headers.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

We haven't supported compiling ObjC1 for a long time (and never will again), so
there isn't any reason to keep these separate. This patch replaces
LangOpts::ObjC1 and LangOpts::ObjC2 with LangOpts::ObjC.

Summary: I did not put lang opt check in AvoidSpinlockCheck since OSSpinLock is not objc specific. We won't want to skip it when analyzing some C++ target used by other ObjC sources.

Summary:
This is a small check to avoid throwing objc exceptions.
In specific it will detect the usage of @throw statement and throw warning.
