Clang currently croaks on the following:
struct X1 {
struct X2 {
int L = ([] (int i) { return i; })(2);
};
};
asserting that the containing lexical context of the lambda is not Sema's cur context, when pushing the lambda's decl context on.
This occurs because (prior to this patch) getContainingDC always returns the non-nested class for functions at class scope (even for inline member functions of nested classes (to account for delayed parsing of their bodies)). The patch addresses this by having getContainingDC always return the lexical DC for a lambda's call operator.

Summary:
MSVC destroys arguments in the callee from left to right. Because C++
objects have to be destroyed in the reverse order of construction, Clang
has to construct arguments from right to left and destroy arguments from
left to right.
This patch fixes the ordering by reversing the order of evaluation of
all call arguments under the MS C++ ABI.
Fixes PR18035.

I'd misunderstood getIndirect() to mean that the argument should be passed
as a pointer at the ABI level, with the ByVal argument choosing caller-copy
semantics over no-caller-copy (callee-copy-on-write) semantics. But
getIndirect(x) actually means that x is passed by pointer at the IR
level but (at least on all other targets I looked at) directly at the
ABI level. getIndirect(x, false) selects a pointer to a caller-made
copy, which is what SystemZ was aiming for.
This fixes a miscompilation of c-index-test. Structure arguments were being
passed by pointer, but no copy was being made, so a write in the callee
stomped over a caller's local variable.

We would lose track of the mangling number assigned to the original
declaration which would cause us to create manglings that didn't match
the Itanium C++ specification.
e.g. Two static fields with the same name inside of a function template
would receive the same mangling with LLVM fixing up the second field so
they wouldn't collide. This would create an incompatibility with other
compilers following the Itanium ABI.
I've confirmed that the new mangling is identical to the ones generated
by icc and gcc.
N.B. This was uncovered while working on Microsoft mangler.

In trunk, we can use features as below:
aarch64-registered-target
hexagon-registered-target
msp430-registered-target
r600-registered-target
systemz-registered-target
xcore-registered-target
Each of them, as below, implies corresponding subtargets:
arm-registered-target -- arm, thumb
mips-registered-target -- mips, mips64, mips64el, mipsel
nvptx-registered-target -- nvptx, nvptx64
sparc-registered-target -- sparc, sparcv9
x86-registered-target -- x86, x86-64
They will be renamed:
cppbackend-registered-target -- was "cpp". Unused in trunk.
powerpc-registered-target -- was "ppc32", "ppc64" and "ppc64le".
The feature "asserts" is also taken from llvm-config.

another initializer via a call on 'self'.
A secondary initializer is an initializer method not marked as a designated
initializer within a class that has at least one initializer marked as a
designated initializer.

If the interface declaration does not have methods marked as designated

Before, there SourceManager would not return a FileEntry for a
SourceLocation of a macro expansion (if the header name itself is
defined in a macro). We'd then fallback to assume that the module
currently being built is the including module. However, in this case we
are actually interested in the spelling location of the filename loc in
order to derive the including module.

This makes it possible to build the clang-format vs plugin from the cmake build.
It is a hack, as it shells out to "devenv" to actually build it, but it's hidden
away in a corner behind a flag, and it provides a convenient way of building the
plug-in from the command-line together with the rest of clang.
