Some users (clang, libTooling) require this. After this patch we can remove
the calls to getenv("PWD") from clang.

Fixed a case where GCC was emitting a DW_TAG_class_type that has a DW_AT_declaration set to true, yet the class actually contains a definition for the class in that DIE.

CXXPseudoDestructorExprs may not contain a type.  PR16852.

[objc-arc] Track if we encountered an additive overflow while computing {TopDown,BottomUp}PathCounts and do nothing if it occurred.

I fixed the aforementioned problems that came up on some of the linux boxes.
Major thanks to Nick Lewycky for his help debugging!

Summary:
Source-centric tools need access to the location of a C++11
lambda expression's capture-default ('&' or '=') when it's present.
It's possible for them to find it by re-lexing and re-implementing
rules that Clang's parser has already applied, but the cost of storing
the SourceLocation and making it available to them is 32 bits per
LambdaExpr (a small delta, proportionally), and the simplification in
client code is significant.

This moves removeUnreachableBlocksFromFn from SimplifyCFGPass.cpp
to Utils/Local.cpp and uses it to replace the implementation of
llvm::removeUnreachableBlocks, which appears to do a strict subset
of what removeUnreachableBlocksFromFn does.

comparing non-reference function parameters.  The qualifiers don't matter for
comparisons.

This is a re-commit of r187769, which was accidentially reverted in r187770,
with a simplification at the suggestion of Eli Friedman.

I need to go through all the runtime routine list and see if there
are any more I need to add for mips16 floating point. Prototypes must
be correct or else I don't know to add a helper function call.

[stackprotector] Simplify SP Pass so that we emit different fail basic blocks for each fail condition.

This patch decouples the stack protector pass so that we can support stack
protector implementations that do not use the IR level generated stack protector
fail basic block.

No codesize increase is caused by this change since the MI level tail merge pass
properly merges together the fail condition blocks (see the updated test).

[arcmt] When handling unbridged casts, handle the body of BlockDecl separately because ParentMap does not record

Use it to avoid repeating ourselves too often. Also store MVT::SimpleValueType
in the TTI tables so they can be statically initialized, MVT's constructors
create bloated initialization code otherwise.

This fixes a problem when the path separator in the include/exclude
directory is different (e.g. "\" vs. "/") from the path separator in
the file path we are modifying.

This includes special members (copy/default ctor, copy assign, default
ctor) and template specializations for member function templates.

Good for a 5% decrease (1.80 to 1.71 GB) in size on Clang+LLVM's .dwo

This is necessary to allow Clang to only emit implicit members when
there is code generated for them, rather than whenever they are ODR
used.

The compiler was warning about using | on a uintptr_t and bool:

  Object/ELFObjectFile.h(131) : warning C4805: '|' : unsafe
  mix of type 'uintptr_t' and type 'bool' in operation

I think the warning might be useful in other cases, so I added
a cast instead of disabling it altogether.
