Fix PR16454: Don't #include altivec.h when preprocessing assembly.
When the -maltivec flag is present, altivec.h is auto-included for the
compilation. This is not appropriate when the job action is to
preprocess a file containing assembly code. So don't do that.
I was unable to convert the test in the bug report into a regression
test. The original symptom was exposed with:
% touch x.S
% ./bin/clang -target powerpc64-unknown-linux-gnu -maltivec -S -o - x.S
I tried this test (and numerous variants) on a PPC64 system:
----------------------------------------------------------------------------
// RUN: touch %t
// RUN: %clang -maltivec -S %t -o - | FileCheck %s
// Verify that assembling an empty file does not auto-include altivec.h.
// CHECK-NOT: static vector
----------------------------------------------------------------------------
However, this test passes for some reason even on a clang built
without the fix. I'd be happy to add a test case but at this point
I'm not able to figure one out, and I don't want to hold up the patch
unnecessarily. Please let me know if you have ideas.

bl __tls_get_addr(sym@tlsld)
bl __tls_get_addr(sym@tlsgd)
which generates two fixups. The current implementation of this causes
problems with recognizing this form in the asm parser. To fix this,
this patch reworks operand processing for this special form by using
a single operand to hold both __tls_get_addr and sym@tlsld and defining
a print method to output the above form, and an encoding method to
generate the two fixups.
As a side simplification, the patch replaces the two instruction
patterns BL8_NOP_TLSGD and BL8_NOP_TLSLD by a single BL8_NOP_TLS,

No functionality change. It should suffice to check the type of a debug info

[PowerPC] Support TLS variables in debug info
This adds an implementation of getDebugThreadLocalSymbol for
(64-bit) PowerPC. This needs to return a generic MCExpr
since on ppc64, we need to add a bias of 0x8000 to the
value returned by the R_PPC64_DTPREL64 relocation.

[DebugInfo] Allow getDebugThreadLocalSymbol to return MCExpr
This allows getDebugThreadLocalSymbol to return a generic MCExpr
instead of just a MCSymbolRefExpr.
This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.

[DebugInfo] Introduce DIEExpr variant of DIEValue to hold MCExpr values
This partially reverts r185202 and restores DIELabel to hold plain
MCSymbol references. Instead, we add a new subclass DIEExpr of

Matthew Dempsky: In libc++'s <locale>, there's already dependence on an snprintf_l
implementation and all of the char buffers readily have their
allocated size available, so we can easily use snprintf_l instead of
sprintf_l.
This avoids OpenBSD's linker warnings against using sprintf and
vsprintf.

[ms-cxxabi] Mangle variadic template parameter packs
Unlike Itanium, there is no code to indicate the beginning of a
parameter pack. I tested this with MSVC 2013, which is the only version
that implements variadic templates so far.
This is needed to compile APInt.cpp for the MS C++ ABI.

More fixes for block mangling.
Make sure we properly treat names defined inside a block as local
names. There are basically three fixes here. One, correctly
treat blocks as a context where we need to use local-name mangling using
the new isLocalContainerContext helper. Two, make
CXXNameMangler::manglePrefix handle local names in a consistent way.
Three, extend CXXNameMangler::mangleLocalName so it can mangle a block
correctly.

Bill Fisher: This patch fixes a bug where the regex parser doesn't advance the pointer after reading the third character of an octal escape (in awk mode).
That is, regex{"\141", awk} results in the regular expression /a1/ instead of just /a/.

[analyzer] Pointers-to-members are (currently) Locs, not NonLocs.
While we don't model pointers-to-members besides "null" and "non-null",
we were using Loc symbols for valid pointers and NonLoc integers for the
null case. This hit the assert committed in r185401.
Fixed by using a true (Loc) null for null member pointers.
