CodeGen: Don't emit a thread-wrapper if we can't touch the backing variable

OS X TLS has all accesses going through the thread-wrapper function and
gives the backing thread-local variable internal linkage.  This means
that thread-wrappers must have WeakAnyLinkage so that references to the
internal thread-local variables do not get propagated to other code.

It also means that translation units which do not provide a definition
for the thread-local variable cannot attempt to emit a thread-wrapper
because the thread wrapper will attempt to reference the backing
variable.

[PowerPC] Fix invalid displacement created by LocalStackAlloc

This commit fixes a bug in PPCRegisterInfo::isFrameOffsetLegal that
could result in the LocalStackAlloc pass creating an MI instruction
out-of-range displacement:
        %vreg17<def> = LD 33184, %vreg31; mem:LD8[%g](align=32)
        %G8RC:%vreg17 G8RC_and_G8RC_NOX0:%vreg31
(In final assembler output the top bits are stripped off, resulting
in a negative offset loading from below the stack pointer.)

Common code expects the isFrameOffsetLegal routine to verify whether
adding a given offset to the offset already present in the instruction
results in a valid displacement.  However, on PowerPC the routine
did not take the already present instruction offset into account.

This commit fixes isFrameOffsetLegal to add the instruction offset,
and updates a local caller (needsFrameBaseReg) to no longer add the
instruction offset itself before calling isFrameOffsetLegal.

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.

3) Don't import termios when initializing the interpreter.  This
   is part of a larger effort to remove the dependency on termios
   since it is not available on Windows.  This particular instance
   was unnecessary and unused.

produce inlinable call sites without locations when the caller has debug
info (in the one case where I could find that this occurred). This
updates the PR20038 test case to be what clang now produces, and readds
the assertion that had to be removed due to this bug.

I've also beefed up the debug info verifier to help diagnose these
issues in the future, and I hope to add checks to the inliner to just
assert-fail if it encounters this situation. If, in the future, we

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.

Provide -verify support to match "any" line for diagnostics in included files.

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.)
