The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
- Manual change to APInt
- Manually chage DOCS as regex doesn't match it.
In the transition period the DEBUG() macro is still present and aliased
to the LLVM_DEBUG() one.

This implements a new table-gen emitter to create tables for
a wasm disassembler, and a dissassembler to use them.
Comes with 2 tests, that tests a few instructions manually. Is also able to
disassemble large .wasm files with objdump reasonably.
Not working so well, to be addressed in followups:
- objdump appears to be passing an incorrect starting point.
- since the disassembler works an instruction at a time, and it is
disassembling stack instruction, it has no idea of pseudo register assignments.
These registers are required for the instruction printing code that follows.
For now, all such registers appear in the output as $0.

Summary:
Previously, a extending load was represented at (G_*EXT (G_LOAD x)).
This had a few drawbacks:
* G_LOAD had to be legal for all sizes you could extend from, even if
registers didn't naturally hold those sizes.
* All sizes you could extend from had to be allocatable just in case the
extend went missing (e.g. by optimization).
* At minimum, G_*EXT and G_TRUNC had to be legal for these sizes. As we
improve optimization of extends and truncates, this legality requirement
would spread without considerable care w.r.t when certain combines were
permitted.
* The SelectionDAG importer required some ugly and fragile pattern
rewriting to translate patterns into this style.
This patch changes the representation to:
* (G_[SZ]EXTLOAD x)
* (G_LOAD x) any-extends when MMO.getSize() * 8 < ResultTy.getSizeInBits()
which resolves these issues by allowing targets to work entirely in their
native register sizes, and by having a more direct translation from
SelectionDAG patterns.
Each extending load can be lowered by the legalizer into separate extends
and loads, however a target that supports s1 will need the any-extending
load to extend to at least s8 since LLVM does not represent memory accesses
smaller than 8 bit. The legalizer can widenScalar G_LOAD into an
any-extending load but sign/zero-extending loads need help from something
else like a combiner pass. A follow-up patch that adds combiner helpers for
for this will follow.
The new representation requires that the MMO correctly reflect the memory
access so this has been corrected in a couple tests. I've also moved the
extending loads to their own tests since they are (mostly) separate opcodes
now. Additionally, the re-write appears to have invalidated two tests from
select-with-no-legality-check.mir since the matcher table no longer contains
loads that result in s1's and they aren't legal in AArch64 anymore.

Previously for instructions like fxsave we would print "opaque ptr" as part of the memory operand. Now we print nothing.
We also no longer accept "opaque ptr" in the parser. We still accept any size to be specified for these instructions, but we may want to consider only parsing when no explicit size is specified. This what gas does.

See r331124 for how I made a list of files missing the include.
I then ran this Python script:
for f in open('filelist.txt'):
f = f.strip()
fl = open(f).readlines()
found = False
for i in xrange(len(fl)):
p = '#include "llvm/'
if not fl[i].startswith(p):
continue
if fl[i][len(p):] > 'Config':
fl.insert(i, '#include "llvm/Config/llvm-config.h"\n')
found = True
break
if not found:
print 'not found', f
else:
open(f, 'w').write(''.join(fl))
and then looked through everything with `svn diff | diffstat -l | xargs -n 1000 gvim -p`
and tried to fix include ordering and whatnot.
No intended behavior change.

When debugging test failures with -vv (or -v in the case of the
internal shell), this makes it easier to locate the RUN line that
failed. For example, clang's test/Driver/linux-ld.c has 892 total RUN
lines, and clang's test/Driver/arm-cortex-cpus.c has 424 RUN lines
after concatenation for line continuations.
When reading the generated shell script, this also makes it easier to
locate the RUN line that produced each command.
To support reporting RUN line numbers in the case of the internal
shell, this patch extends the internal shell to support the null
command, ":", except pipelines are not supported.

lit's util.which() would check if the passed-in path existed directly,
and if so return it as-is. This is never the case when running llvm's, clang's,
or lld's tests normally. But when running `./llvm-lit path/to/clang/test`
with a cwd of llvm-build/bin, this if would detect that clang exists at path
'clang' and return 'clang' as the discovered clang binary -- and then lit would
use the " clang " -> "*** Do not use 'clang' in tests, use '%clang'. ***"
substitution to replace that with a broken test. By removing this early
return, lit ends up with the usual absolute path and everything works even
in this uncommon case.

The script was using Python's difflib module to calculate the number of
lines changed so that it could report it in its status output. It turns

Summary:
This is a small refactoring to extract the svn checkout code from the
build script used inside the docker image.
This would give more flexibility if more than a single invocation of
cmake is needed inside the docker image.
User-facing interface (build_docker_image.sh) hasn't changed, only the
internal scripts running inside the build container are affected.

This patch ensures that the pfm issue counter tables are the correct size, accounting for the invalid resource entry at the beginning of the resource tables.
It also fixes an issue with pfm failing to match event counters due to a trailing comma added to all the event names.
I've also added a counter comment to each entry as it helps locate problems with the tables.
Note: I don't have access to a SandyBridge test machine, which is the only model to make use of multiple event counters being mapped to a single resource. I don't know if pfm accepts a comma-seperated list or not, but that is what it was doing.

There are two versions of to_string used by TestRunner.py. The one defined
in TestRunner.py and the one defined in utils/lit/lit/util.py. The util.py
version is superior to the TestRunner.py version.
This change removes the duplicate to_string in TestRunner.py in favor of
always using the version from util.py. Beside removing duplicate code, this
makes it easier to debug TestRunner.py since only one version of to_string
is used.
