We already have support for using c++ headers from a custom location.
...
Before this patch we would still link with the system libstdc++. It worked
fine most of the time, but would break if the used headers were a lot newer
than the system libraries.

headers the user selected.
This fixes, for example, using 4.5 headers in a system with gcc 4.1.

Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. This
...
matches GCC behavior which libstdc++ uses to limit #warning-based
messages about deprecation.
The machinery involves threading this through a new '-fdeprecated-macro'
flag for CC1. The flag defaults to "on", similarly to -Wdeprecated. We
turn the flag off in the driver when the warning is turned off (modulo
matching some GCC bugs). We record this as a language option, and key
the preprocessor on the option when introducing the define.
A separate flag rather than a '-D' flag allows us to properly represent
the difference between C and C++ builds (only C++ receives the define),
and it allows the specific behavior of following -Wdeprecated without
potentially impacting the set of user-provided macro flags.

There were some frustrating problems with the implementation of
...
-Wwrite-strings. First and foremost, once the positive form of the flag
was passed, it could never be disabled by passing -Wno-write-strings.
Also, the diagnostic engine couldn't in turn use -Wwrite-strings to
control diagnostics (as GCC does) because it was essentially hijacked to
drive the language semantics.
Fix this by giving CC1 a clean '-fconst-strings' flag to enable
const-qualified strings in C and ObjC compilations. Corresponding
'-fno-const-strings' is also added. Then the driver is taught to
introduce '-fconst-strings' in the CC1 command when '-Wwrite-strings'
dominates.
This entire flag is basically GCC-bug-compatibility driven, so we also
match GCC's bug where '-w' doesn't actually disable -Wwrite-strings. I'm
open to changing this though as it seems insane.

Add an option to suppress include stack printing on note diagnostics.
...
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.

Frontend: Add a more explicit -backend-option flag for passing backend command
...
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).

Introduce FindTargetProgramPath to check for a target-specific helper
...
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.

Memorize presence/absence of -nostdlib in Driver.
...
Drop program paths on NetBSD (unused). Only include lib dir, if
-nostdlib is absent. Use = to allow --sysroot to work.

Remember sysroot in Driver. Pass it down to ld for NetBSD, FreeBSD
...
and DragonFly. Use the --sysroot= form for Linux. Fix handling of =
prefix for -B.

Driver: Forward -traditional and -traditional-cpp in preprocessing modes.
...
- 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.
