Drive-by fixing some incorrect types where a for loop would be improperly using ObjCInterfaceDecl::protocol_iterator. No functional changes in these cases.

This makes Clang take advantage of the recent IR addition of a
"failure" memory ordering requirement. As with the "success" ordering,
we try to emit just a single version if the expression is constant,
but fall back to runtime detection (to allow optimisation across
function-call boundaries).

Passing a pointer to an uninitialized memory buffer is normally okay,
but if the function is declared to take a pointer-to-const then it's
very unlikely it will be modifying the buffer. In this case the analyzer
should warn that there will likely be a read of uninitialized memory.
This doesn't check all elements of an array, only the first one.
It also doesn't yet check Objective-C methods, only C functions and
C++ methods.
This is controlled by a new check: alpha.core.CallAndMessageUnInitRefArg.

When building an AST file, we don't want to output HeaderFileInfo
structures for files that are not actually used as headers in the
current context. This can lead to assuming that unrelated files have
include counts of 0, defeating multiple-include prevention.
This is accomplished by adding an IsValid bit to the HFI.

r203272 enables generation of a Qt Compressed Help file for the LLVM source
code.
As a consequence, this change brings the same capabilities to Clang while
reusing these two variables:
LLVM_ENABLE_DOXYGEN_QT_HELP
LLVM_DOXYGEN_QHELPGENERATOR_PATH
and adding
CLANG_DOXYGEN_QCH_FILENAME="org.llvm.clang.qch"
CLANG_DOXYGEN_QHP_NAMESPACE="org.llvm.clang"
CLANG_DOXYGEN_QHP_CUST_FILTER_NAME="Clang ${CLANG_VERSION}"
CLANG_DOXYGEN_QHP_CUST_FILTER_ATTRS="Clang,${CLANG_VERSION}"

This was leading to bad formatting, e.g.:
Before:
f(^{
@autoreleasepool {
if (a) {
g();
}
}
});
After:
f(^{
@autoreleasepool {
if (a) {
g();
}
}
});

const-qualified parameter type and the defined with a non-const-qualified
parameter type, the parameter is not const inside its body. Ensure that
the type we use when instantiating the body is the right one. Patch by
suyog sarda!
This is still rather unsatisfactory; it seems like it might be better to
instantiate at least the function parameters, and maybe the complete function
declaration, when we instantiate the definition for such a member function
(instead of reusing the declaration from inside the instantiated class
definition).

that implicitly converts to 'bool' (such as pointers, and the first operand of
?:). Clean up issues found by this. Patch by Stephan Tolksdorf!

They're already defined in ia32intrin.h, and this would cause including Intrin.h
in 64-bit mode to fail because of conflicting types. Update ms-intrin.cpp to
also run in 64-bit mode to catch things like this.

This updates CodeGenPGO to use the ProfileDataReader introduced to
llvm in r203703 and the new API for writing out the profile introduced
to compiler-rt in r203710.

When a struct has bitfields overlapping with other members
(as required by the AAPCS), clang uses a packed struct to
represent this. If such a struct is large enough for clang to
pass it as a byval pointer (>64 bytes), we need to set the
alignment of the argument to match the original type.
