This changes clang to match GCC's behavior for __extension__, which temporarily
disables the -pedantic flag. Warnings that are enabled without -pedantic
are not affected. Besides the general goodness of matching GCC's precedent,
my motivation for this is that macros in the arm_neon.h header need to use
__extension__ to avoid pedantic complaints about their use of statement
expressions, yet we still want to warn about incompatible pointer arguments
for those macros.

the command line options (at least according to GCC's documentation). GCC 4.2
didn't appear to actually do this, but it seems like that has been fixed in
later release, so we will follow the docs.

- This fixes a host of obscure bugs with regards to how warning mapping options composed with one another, and I believe makes the code substantially easier to read and reason about.

- No actual functionality change for now, we still also use the diag::Mapping::{MAP_WARNING_NO_ERROR,MAP_ERROR_NO_FATAL,MAP_WARNING_SHOW_IN_SYSTEM_HEADER} for a little while longer.

- The TextDiagnosticPrinter code is still fragile as it is just "reverse engineering" what the diagnostic engine is doing. Not my current priority to fix though.
llvm-svn: 140752
DiagnosticsEngine::setDiagnosticGroup{ErrorAsFatal,WarningAsError} methods which
more accurately model the correct API -- no internal change to the diagnostics
engine yet though.
- Also, stop honoring -Werror=everything (etc.) as a valid (but oddly behaved) option.

predefines based on the output of GCC as well as the CPU predefines.
Invert tests for __AVX__, Clang's AVX feature is hard coded off still.
Switch Atom from 'SSE3' to 'SSSE3'. This matches GCC's behavior, Intel's
documentation, and ICC's documentation (such as I could dig up).
Switch Athlon and Geode to enable 3dnowa rather than just 3dnow and
nothing (resp.).
llvm-svn: 140692
fallthrough now that we're working with a switch. Also remove a dubious
"feature" regarding k6 processors and 3dnow and leave a fixme... Not
that anyone is likely to care about correct tuning for k6 processors
with and w/o 3dnow...

selected CPU model to the enumeration. This parses the string
representation once using a StringSwitch on SetCPU. It returns an error
for strings which are not recognized (yay!). Finally it replaces
ridiculous if-chains with switches that cover all enumerators.
The last change required adding several missing entries to the features
function. These were obvious on inspection. Yay for a pattern that gives
warnings when we miss one.
No new test cases yet, as I want to get the 64-bit errors working first.
I'll then start fleshing out the testing more. Currently I'm primarily
testing on Linux, but I'm hoping check whether there are interesting
differences on darwin before long...

it an error if a CPU is provided for a target that doesn't implement
logic handling CPU settings, to match the ABI settings. It also removes
the CPU parameter from the getDefaultFeatures method. This parameter was
always filled in with the same value as setCPU was called with, and at
this point every single target implementation that referenced the CPU
within this function has needed to store the CPU via setCPU anyways in
order to implement other interface points.

is *very* much a WIP that I'll be refining over the next several
commits, but I need to get this checkpoint in place for sanity.
This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.
Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.

of a ContentCache, since multiple FileIDs can have the same ContentCache
but the expanded macro arguments locations will be different.

change __builtin_va_list to from a structure to int[4] (same alignment
and size, but with a simpler representation). Patch by David Meyer!

check whether the requested location points inside the precompiled preamble,
in which case the returned source location will be a "loaded" one.
