register extra version information to be printed. This is designed to
allow those tools which link in various targets to also print those
registered targets under --version.
Currently this printing logic is embedded into the Support library
directly; a huge layering violation. This is the first step to hoisting
it out into the tools without adding lots of duplicated code.

so that we have one, simple way to map from global bit offsets to
local bit offsets. Eliminates a number of loops over the chain, and
generalizes for more interesting bit remappings.
Also, as an amusing oddity, we were computing global bit offsets
*backwards* for preprocessed entities (e.g., the directly included PCH
file in the chain would start at offset zero, rather than the original
PCH that occurs first in translation unit). Even more amusingly, it
made precompiled preambles work, because we were forgetting to adjust
the local bit offset to a global bit offset when storing preprocessed
entity offsets in the ASTUnit. Two wrongs made a right, and now
they're both right.

AnalysisBasedWarnings Sema layer and out of the Analysis library itself.
This returns the uninitialized values analysis to a more pure form,
allowing its original logic to correctly detect some categories of
definitely uninitialized values. Fixes PR10358 (again).
Thanks to Ted for reviewing and updating this patch after his rewrite of
several portions of this analysis.

methods, including indirectly overridden methods like those
declared in protocols and categories. There are mismatches
that we would like to diagnose but aren't yet, but this
is fine for now.
I looked at approaches that avoided doing this lookup
unless we needed it, but the infer-related-result-type
checks were doing it anyway, so I left it with the same
fast-path check for no previous declartions of that
selector.

This was previously not-const only because it has to lazily construct a chain
of ivars the first time it is called (and after the chain is invalidated).
In practice, all the clients were just const_casting their const Decls;
all those now-unnecessary const_casts have been removed.

will be rejected with a compilation error in ARC mode, and a compiler warning otherwise.
This may cause breakage in non-arc (and arc) tests which don't expect warning/error. Feel free
to fix the tests, or reverse the patch, if I am unavailable. // rdar://9818354 - WIP

type IDs into a single place, and make sure that all of the callers
use the appropriate functions to do the mapping. Since the mapping is
still the identity function, this is essentially a no-op.

(e.g. ${var%S}). this might already be the default if your variable is of an aggregate type
new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset
- the restricted list of children obeys the typical rules (e.g. summaries prevail over children)
- one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible
- to provide a synthetic children list use the "type synth add" command, as in:
type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4]
(you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported)
- a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones

the way to go. Doing this here will prevent several node matches later,
and would have to force looking all the way through several
VINSERTF128/VEXTRACTF128 chains to optimize simple things.

and was actually very wrong, fix it and make it simpler. Also remove the
ConcatVectors function, which is unused now.
- Fix a introduction of useless nodes in r126664 and r126264. The
VUNPCKL* should never be introduced cause we don't want duplicate
nodes for 128 AVX and non-AVX modes, the actual instruction
difference only exists during isel, but not for target specific DAG
nodes. We only introduce V* target nodes when there is no 128-bit
version already there.
- Fix a fragile test and make it more useful.

such that every declaration ID loaded from an AST file will go through
a central local -> global mapping function. At present, this change
does nothing, since the local -> global mapping function is the
identity function.
This is the mechanical part of the refactoring; a follow-up patch will
address a few remaining areas where it's not obvious whether we're
dealing with local or global IDs.
