These stacks are often less important than those on primary diagnostics.
As the number of notes grows, this becomes increasingly important. The
include stack printing is clever and doesn't print stacks for adjacent
diagnostics from the same file, but when a note is in between a sequence
of errors in a header file, and the notes all refer to some other file,
we end up getting a worst-case ping-pong of include stacks that take up
a great deal of vertical space.
Still, for now, the default behavior isn't changed. We can evaluate user
feedback with the flag.
Patch by Richard Trieu, a couple of style tweaks from me.

default for -fwrapv if that flag isn't specified explicitly. We always
prefer an explict setting of -fwrapv when present. Also adds support for
-fno-wrapv to allow disabling -fwrapv even when -fno-strict-overflow is
passed.

line options, instead of leveraging the blanket -mllvm option.
- This allows using the frontend itself without requiring the backend have
those options available (i.e., if the target wasn't built).

program and fallback to plain version otherwise. Use this for the NetBSD
target to make it try e.g. i486--netbsdelf-as and -ld for target
i486--netbsdelf.

- We don't really support the majority of the horrible -traditional-cpp
behavior, but it is unlikely that we ever will either. This allows us to
start trying to use clang as a /usr/bin/cpp replacement and see what pieces
of -traditional-cpp mode people actually care about.

Issue this as an IR-gen error; it's not really worthwhile doing this
"right", i.e. in Sema, because IR gen knows a lot of tricks beyond
what the constant evaluator knows.

retrieve the library paths from the ToolChain object instead.
Copy the relevant code from linuxtools::Link::ConstructJob(), and
replace the std::string stuff with llvm::StringRef, while we're here.

of -fexceptions to disably C++ exceptions. The correct code was in the
ObjC branch, this just mirrors that logic on the C++ side of things.
Thanks to John Wiegley for pointing this out.

C++ exceptions, even when exceptions have been turned off using -fno-exceptions.
Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions.
C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and
-fno-objc-exceptions.

The rest have/create implicit dependencies between checkers and need to be handled differently.
llvm-svn: 125559
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
register them with the CheckerManager which will be the entry point for all checker-related functionality.
Currently only the self-initialization checker takes advantage of the new mechanism.
