Douglas Gregor 3120d2c389 Eliminate the redundancy between source-file information in the source
manager block and input-file information in the control block. The
source manager entries now point back into the control block. Input
files are now lazily deserialized (if validation is disabled). Reduces
Cocoa's PCH by the ~70k I added when I introduced the redundancy in
r166251.

Enrico Granata e3e91517ff <rdar://problem/12437442>
Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar*
If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was
no trivial way for us to change the SP inside an SBValue on the fly
This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM)
As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython
Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases)

Hal Finkel 931c52b84c BBVectorize should ignore unreachable blocks.
Unreachable blocks can have invalid instructions. For example,
jump threading can produce self-referential instructions in
unreachable blocks. Also, we should not be spending time
optimizing unreachable code. Fixes PR14133.

Patch by Quentin Colombet <qcolombet@apple.com>

Original description:
"""
The attached patch is the first step to have a better control on Oz related optimizations.
The Oz optimization level focuses on code size, thus I propose to add an attribute called ForceSizeOpt.

Allow type searches to specify a type keyword when searching for type. Currently supported type keywords are: struct, class, union, enum, and typedef.

Tobias Grosser 6c8e696618 cmake: Use suffix for shared modules instead of the one for shared libraries
On Linux there is no difference between shared modules and shared libaries, both
are '.so' files. However, on darwin only shared modules are '.so' files. Shared
libraries have the '.dynlib' suffix.

Fix test cases on darwin by expecting a shared module suffix for Polly instead
of a shared library suffix.

This fixes PR14135

Benjamin Kramer f77f224df9 Revert r166390 "LoopIdiom: Replace custom dependence analysis with LoopDependenceAnalysis."
It passes all tests, produces better results than the old code but uses the
wrong pass, LoopDependenceAnalysis, which is old and unmaintained. "Why is it
still in tree?", you might ask. The answer is obviously: "To confuse developers."

Just swapping in the new dependency pass sends the pass manager into an infinte
loop, I'll try to figure out why tomorrow.

Benjamin Kramer 3ae8bc68af LoopIdiom: Replace custom dependence analysis with LoopDependenceAnalysis.
Requires a lot less code and complexity on loop-idiom's side and the more
precise analysis can catch more cases, like the one I included as a test case.
This also fixes the edge-case miscompilation from PR9481. I'm not entirely
sure that all cases are handled that the old checks handled but LDA will
certainly become smarter in the future.

Richard Smith db2630fb04 Unrevert r166268, reverted in r166272, with a fix for the issue which Nick
found: if an overloaded operator& is present before a template definition,
the expression &T::foo is represented as a CXXOperatorCallExpr, not as a
UnaryOperator, so we didn't notice that it's permitted to reference a non-static
data member of an unrelated class.

While investigating this, I discovered another problem in this area: we are
treating template default arguments as unevaluated contexts during substitution,
resulting in performing incorrect checks for uses of non-static data members in
C++11. That is not fixed by this patch (I'll look into this soon; it's related
to the failure to correctly instantiate constexpr function templates), but was
resulting in this bug not firing in C++11 mode (except with -Wc++98-compat).

Original message:

PR14124: When performing template instantiation of a qualified-id outside of a
class, diagnose if the qualified-id instantiates to a non-static class member.
