Even though we previously correctly detected the multi-dimensional access
pattern for accesses with a certain base address, we only delinearized
non-affine accesses to this address. Affine accesses have not been touched and
remained as single dimensional accesses. The result was an inconsistent
description of accesses to the same array, with some being one dimensional and
some being multi-dimensional.
This patch ensures that all accesses are delinearized with the same
dimensionality as soon as a single one of them has been detected as non-affine.
While writing this patch, it became evident that the options
-polly-allow-nonaffine and -polly-detect-keep-going have not been properly
supported in case delinearization has been turned on. This patch adds relevant
test coverage and addresses these issues as well. We also added some more
documentation to the functions that are modified in this patch.
This fixes llvm.org/PR20123

At the moment we assume that only elements of identical size are stored/loaded
to a certain base pointer. This patch adds logic to the scop detection to verify
this.

Check that the post RA scheduler is being skipped, regardless of
whether it's the top-down list latency scheduler or the post-RA
MI scheduler.

anyway /Vol doesn't complete correctly either. Somehow we're chopping the names
up incorrectly before passing them into the completer.

* Fixes the local stack variable return pointer usage in NativeThreadLinux::GetName().
* Changes NativeThreadProtocol::GetName() to return a std::string.
* Adds a unit test to verify thread names don't regress in the future. Currently only run on Linux since I know default thread names there.

Similar to my previous -exports-trie option, the -rebase option dumps info from
the LC_DYLD_INFO load command. The rebasing info is a list of the the locations
that dyld needs to adjust if a mach-o image is not loaded at its preferred
address. Since ASLR is now the default, images almost never load at their
preferred address, and thus need to be rebased by dyld.

The raw profiles that are generated in compiler-rt always add padding
so that each profile is aligned, so we can simply treat files that
don't have this property as malformed.

enabled. A good chunk of the MIsNeedChainEdge() is logic that is valid and should be applied even for targets
that are not using for alias analysis.

Apparently, PEEKUSER/POKEUSER is something x86 specific, so I had to rework it for AArch64. This fixes assertion that occurs whenever lldb started on AArch64 device tried to read PC register (or any other register)
See http://reviews.llvm.org/D5232 for more details.

Vector MUL/MLAs have tied operands, which gives us extra constraints
that we currently can't handle. Instead of silently doing the wrong
thing, remove support to be readded later properly.

Defs are seen before uses, so a def without the kill flag doesn't necessarily
mean that the register is not killed on that instruction. It may be killed
in a later use operand.

As far as I can tell UTF-8 has been supported since the beginning of Python's
codec support, and it's the de facto standard for text these days, at least
for primarily-English text. This allows us to put Unicode into lit RUN lines.
