Get the python scripting interface working on Windows.
This patch fixes a number of issues with embedded Python on
Windows. In particular:
1) The script that builds the python modules was normalizing the
case of python filenames during copies. The module name is
the filename, and is case-sensitive, so this was breaking code.
2) Changes the build to not attempt to link against python27.lib
(e.g. the release library) when linking against msvcrt debug
library. Doing a debug build of LLDB with embedded python
support now requires you to provide your own self-compiled
debug version of python.

If the name in a friend declaration is neither qualified nor a

has been previously declared shall not consider any scopes outside the

MSVC does not implement that rule for types. If there is a type in an

updates the PR20038 test case to be what clang now produces, and readds

issues in the future, and I hope to add checks to the inliner to just

[DAG] Further improve the logic in DAGCombiner that folds a pair of shuffles into a single shuffle if the resulting mask is legal.
This patch teaches the DAGCombiner how to fold shuffles according to the
following new rules:
1. shuffle(shuffle(x, y), undef) -> x
2. shuffle(shuffle(x, y), undef) -> y
3. shuffle(shuffle(x, y), undef) -> shuffle(x, undef)
4. shuffle(shuffle(x, y), undef) -> shuffle(y, undef)
The backend avoids to combine shuffles according to rules 3. and 4. if
the resulting shuffle does not have a legal mask. This is to avoid introducing
illegal shuffles that are potentially expanded into a sub-optimal sequence of
target specific dag nodes during vector legalization.
Added test case combine-vec-shuffle-2.ll to verify that we correctly triggers
the new rules when combining shuffles.

[PowerPC] ABI support for aligned by-value aggregates
This patch adds support for respecting the ABI and type alignment
of aggregates passed by value. Currently, all aggregates are aligned
at 8 bytes in the parameter save area. This is incorrect for two
reasons:
- Aggregates that need alignment of 16 bytes or more should be aligned
at 16 bytes in the parameter save area. This is implemented by
using an appropriate "byval align" attribute in the IR.
- Aggregates that need alignment beyond 16 bytes need to be dynamically
realigned by the caller. This is implemented by setting the Realign
flag of the ABIArgInfo::getIndirect call.
In addition, when expanding a va_arg call accessing a type that is
aligned at 16 bytes in the argument save area (either one of the
aggregate types as above, or a vector type which is already aligned
at 16 bytes), code needs to align the va_list pointer accordingly.

Allow diagnostic checks that originate in included files to be matched without necessarily determining the line number that the diagnostic occurs on. The new syntax replaces the line number with '*'. This extension is limited to diagnostics in included files and may be used where the include file is not part of the test-suite itself.
Expected uses are for diagnostics originating in system headers, or for users who use -verify in testing 3rd-party library code where the location of diagnostics in header files may change from revision to revision and their precise location is not important to the success of the test-case.

[PowerPC] ABI support for non-Altivec vector types
This patch adds support for passing arguments of non-Altivec vector type
(i.e. defined via attribute ((vector_size (...)))) on powerpc64-linux.
While such types are not mentioned in the formal ABI document, this
patch implements a calling convention compatible with GCC:
- Vectors of size < 16 bytes are passed in a GPR
- Vectors of size > 16 bytes are passed via reference
Note that vector types with a number of elements that is not a power
of 2 are not supported by GCC, so there is no pre-existing ABI to
follow. We choose to pass those (of size < 16) as if widened to the
next power of two, so they might end up in a vector register or
in a GPR. (Sizes > 16 are always passed via reference as well.)

Because the analyzer does not necessarily explore /all/ paths through a program,
