feature; support these options as well.

gcc provides -mmfcrf and -mno-mfcrf for controlling what we call
the mfocrf target feature. Also, PPC is now making use of the
static function AddTargetFeature used by the Mips Driver code.

LLVM/clang prefetch builtin

Configuration macros are macros that are intended to alter how a
module works, such that we need to build different module variants
for different values of these macros. A module can declare its
configuration macros, in which case we will complain if the definition
of a configation macro on the command line (or lack thereof) differs
from the current preprocessor state at the point where the module is
imported. This should eliminate some surprises when enabling modules,
because "#define CONFIG_MACRO ..." followed by "#include
<module/header.h>" would silently ignore the CONFIG_MACRO setting. At
least it will no longer be silent about it.
Configuration macros are eventually intended to help reduce the number
of module variants that need to be built. When the list of
configuration macros for a module is exhaustive, we only need to
consider the settings for those macros when building/finding the
module, which can help isolate modules for various project-specific -D
flags that should never affect how modules are build (but currently do).

This allows resolving top-header filenames of modules to FileEntries when
we need them, not eagerly.
Note that that this breaks ABI for libclang functions
clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders
but this is fine because they are experimental and not widely used yet.

Driver will now error when trying to compile for V2 or V3.
Removal of V2 and V3 support will allow us to simplify the hexagon
back-end.

'R' An address that can be sued in a non-macro load or store.
Including missing positive test case and fixed typo for r176453.
Thanks to Richard Smith for catching this!

'R' An address that can be sued in a non-macro load or store.

isBeforeInTranslationUnit() uses a cache to reduce the expensive work
to compute a common ancestor for two FileIDs. This work is very
expensive, so even caching the latest used FileIDs was a big win.
A closer analysis of the cache before, however, shows that the cache
access pattern would oscillate between a working set of FileIDs, and
thus caching more pairs would be profitable.
This patch adds a side table for extending caching. This side table
is bounded in size (experimentally determined in this case from
a simple Objective-C project), and when the table gets too large
we fall back to the single entry caching before as before.
On Sketch (a small example Objective-C project), this optimization
reduces -fsyntax-only time on SKTGraphicView.m by 5%. This is
for a project that is already using PCH.

This may seem counter-intuitive but the POD-like optimization helps when the
vectors grow into multimegabyte buffers. SmallVector calls realloc which knows
how to twiddle virtual memory bits and avoids large copies.

This allows Clang to detect and deal wih __atomic_* operations properly on
AArch64. Previously we produced an error when encountering them at high
optimisation levels.

Nearly all of these changes are one-to-one replacements; the few that
aren't have to do with custom identifier validation.

Rewriting the same predicates over and over again is bad for code size and
code maintainence. Using the functions in <ctype.h> is generally unsafe
unless they are specified to be locale-independent (i.e. only isdigit and
isxdigit).
The next commit will try to clean up uses of <ctype.h> functions within Clang.

Introduces these negation forms explicitly and uses them to control a new
"altivec" target feature for PowerPC. This allows avoiding generating
Altivec instructions on processors that support Altivec.
The new test case verifies that the Altivec "lvx" instruction is not
used when -fno-altivec is present on the command line.

In cooperation with the LLVM patch, this should implement all scalar front-end
parts of the C and C++ ABIs for AArch64.
This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.
Further reviews would be gratefully received.

factor the realpath calls into FileManager::getCanonicalName() so we
can cache the results of this epically slow operation. 5% speedup on
my modules test, and realpath drops out of the profile.
