It seems SystemZTargetLowering::getTargetNodeName got out of sync with
some recent changes to the SystemZISD opcode list. Add back all the
missing opcodes (and re-sort to the same order as SystemISelLowering.h).

ScheduleDAGInstrs wasn't setting or clearing the kill flags on instructions inside bundles. This led to code such as this
%R3<def> = t2ANDrr %R0
BUNDLE %ITSTATE<imp-def,dead>, %R0<imp-use,kill>
t2IT 1, 24, %ITSTATE<imp-def>
R6<def,tied6> = t2ORRrr %R0<kill>, ...
being transformed to
BUNDLE %ITSTATE<imp-def,dead>, %R0<imp-use>
t2IT 1, 24, %ITSTATE<imp-def>
R6<def,tied6> = t2ORRrr %R0<kill>, ...
%R3<def> = t2ANDrr %R0<kill>
where the kill flag was removed from the BUNDLE instruction, but not the t2ORRrr inside it. The verifier then thought that
R0 was undefined when read by the AND.
This change make the toggleKillFlags method also check for bundles and toggle flags on bundled instructions.
Setting the kill flag is special cased as we only want to set the kill flag on the last instruction in the bundle.

If a class is absent from instantiation and is incomplete, instantiate it as
an incomplete class thus avoiding compiler crash.

This reverts commit r236422, effectively reapplying r236419. ASan
helped me diagnose the problem: the non-leaking logic would free the
ASTConsumer before freeing Sema whenever `isCurrentASTFile()`, causing a
use-after-free in `Sema::~Sema()`.
This version unconditionally frees Sema and the ASTContext before
freeing the ASTConsumer. Without the fix, these were either being freed
before the ASTConsumer was freed or leaked after, but they were always
spiritually released so this isn't really a functionality change.
I ran all of check-clang with ASan locally this time, so I'm hoping
there aren't any more problems lurking.
Original commit message:
Try again to plug a leak that's been around since at least r128011
after coming across the FIXME. Nico Weber tried something similar
in r207065 but had to revert in r207070 due to a bot failure.
The build failure isn't visible anymore so I'm not sure what went
wrong. I'm doing this slightly differently -- when not
-disable-free I'm still resetting the members (just not leaking
them) -- so maybe it will work out this time? Tests pass locally,
anyway.

This fixes errors that occur if a path to the default compiler has spaces or if an argument with spaces is given to compiler (e.g. via -I). (http://reviews.llvm.org/D9357)

EmulateInstructionMIPS64 has been modified to use llvm::MCDisassembler instead of duplicating the decoding logic.
Added emulation of few branch instructions for software single stepping

After r210687, windows_error does nothing but call mapWindowsError.
Other Windows/*.inc files directly call mapWindowsError. This patch
updates Path.inc and Process.inc to do the same.

clang::MacroDefinition now models the currently-defined value of a macro. The

Upgrade instructions:
$ mv llvm/include/llvm/Config/config.h ./config.h.BACKUP
# copy the configure line from line 7 of llvm/config.log

$ mkdir build
$ cd build
# run the configure line, but this time with '../llvm' at the beginning:
$ ../llvm/configure --no-create --no-recursion
These warnings will soon be turned into hard errors after a week. Speak up now

These tests link against host lldb API. Compiler's target triple
must match liblldb triple. Instead of naively skipping i386, I added
a check of the liblldb arch against the compiler target arch.
This is useful for 32 bit API builds (planned for Windows)
Since remote is disabled, we can assume the os is the same.
Also, removed skipIfLinuxClang because it's passing

This change adds location information for the detected regions in Polly when the
required debug information is available.
The JSCOP output format is extended with a "location" field which contains the
information in the format "source.c:start-end"
The dot output is extended to contain the location information for each nested
region in the analyzed function.
As part of this change, the existing getDebugLocation function has been moved
into lib/Support/ScopLocation.cpp to avoid having to include
polly/ScopDetectionDiagnostics.h.

Using GetNumBytesInBuffer() assumes that the stream was not flushed between
the GetNumBytesInBuffer() calls, which may happen to be true or not,
depending on stream policy. tell() always reports the correct stream location.
Do note there are only two more uses of GetNumBytesInBuffer() in LLVM+clang, in
lib/MC/MCAsmStreamer.cpp and lib/Target/R600/InstPrinter/AMDGPUInstPrinter.cpp.
The former may be replacable by tell (needs testing) but while the later can
not be immediatly replaced by tell() as it uses the absolute value of
GetNumBytesInBuffer() rather than the real stream position. Both uses seems
to depend upon flush policy and thus may not work correctly depending upon the
stream behaviour.
Going forward, GetNumBytesInBuffer() should probably be protected, non-accessible
to raw_ostream clients.

OriginalColumn might not be set, so fall back to Location and SourceMgr
in case it is missing. Also initialize end column in case the token is
