Add warnings under -Wc++11-compat, -Wc++98-compat, and -Wc99-compat when a
particular UCN is incompatible with a different standard, and -Wunicode when
a UCN refers to a surrogate character in C++03.

The missing definition check should be in the same category as the
missing ivar validation - in this case, the intent is to invalidate in
the given class, as described in the declaration, but the implementation
does not perform the invalidation. Whereas the MissingInvalidationMethod
checker checks the cases where the method intention is not to
invalidate. The second checker has potential to have a much higher false
positive rate.

Added a new line of information that reports the count of tests that pass, fail or have other things happen to them.
Again no flag to have the dots back. If you care, let us know!

The new annotation allows having methods that only partially invalidate
IVars and might not be called from the invalidation methods directly
(instead, are guaranteed to be called before the invalidation occurs).
The checker is going to trust the programmer to call the partial
invalidation method before the invalidator.This is common in cases when
partial object tear down happens before the death of the object.

The LLDB test suite now shows a progress bar instead of dots when not in verbose mode
If you crave the dots, make your Terminal window smaller than 10 columns :-)
(or ask for a flag to have the dots come back on demand)

This uses a liveness algorithm that does not depend on data from the
LiveVariables analysis, it is the first step towards removing
LiveVariables completely.

check_cxx_symbol_exists requires CMake 2.8.6, so even though I
recommended it to Owen it's probably better to stay away for now.
This check is not technically correct because we're checking <math.h>
but then using <cmath> in the actual code, but if we run into problems we
can do the same sort of dance as isinf() and isnan() where we check /both/
headers and then write a wrapper header around them.

to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of
gcc, where it will silently accept an unknown -Wno-foo option, but will
generate an error for a compile which uses -Wno-foo if that compile also
triggers any warnings.

This may not always be valid, but we were previously just
emitting them raw.

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.

This fixes a couple of bugs and incorrect assumptions,
in total four more piglit tests now pass.

This reverts r171041. This was a nice idea that didn't work out well.
Clang warnings need to be associated with warning groups so that they can
be selectively disabled, promoted to errors, etc. This simplistic patch didn't
allow for that. Enhancing it to provide some way for the backend to specify
a front-end warning type seems like overkill for the few uses of this, at
least for now.

same so we put in the comment field an indicator when we think we are
emitting the 16 bit version. For the direct object emitter, the difference is
important as well as for other passes which need an accurate count of
program size. There will be other similar putbacks to this for various
instructions.

Previously, even when a pre-increment load or store was generated,
we often needed to keep a copy of the original base register for use
with other offsets. If all of these offsets are constants (including
the offset which was combined into the addressing mode), then this is
clearly unnecessary. This change adjusts these other offsets to use the
new incremented address.

This is a follow-up to the cost-model change in r174713 which splits
the cost of a memory operation between the address computation and the
actual memory access. In r174713, this cost is always added to the
memory operation cost, and so BBVectorize will do the same.
Currently, this new cost function is used only by ARM, and I don't
have any ARM test cases for BBVectorize. Assistance in generating some
good ARM test cases for BBVectorize would be greatly appreciated!

Aside from the question of whether we report a warning or an error when we
can't satisfy a requested stack object alignment, the current implementation
of this is not good. We're not providing any source location in the diagnostics
and the current warning is not connected to any warning group so you can't
control it. We could improve the source location somewhat, but we can do a
much better job if this check is implemented in the front-end, so let's do that
instead. <rdar://problem/13127907>

This updates the current references to links that work for me.
In the future, we should update the list of references itself to provide
information on newer architecture variants.
Thanks to Sean Silva for pointing out that the current links were broken!
