This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.

I somehow wrote this fix and then lost it prior to commit. Really sorry
about the noise. This should fix some issues with hacking add_definition

Sometimes, llvm-symbolizer gives wrong results due to incorrect sizes of some symbols. The reason for that was an incorrectly sorted array in computeSymbolSizes. The comparison function used subtraction of unsigned types, which is incorrect. Let's change this to return explicit -1 or 1.

Add unit tests for checking a few tricky instruction sizes. Also remove the old
tests for the instruction sizes, which were clunky and brittle.
Since this is the first set of target-specific unit tests, we need to add some
CMake plumbing. In the future, adding unit tests for a given target will be as
simple as creating a directory with the same name as the target under
unittests/Target. The tests are only run if the target is enabled in
LLVM_TARGETS_TO_BUILD.

In the top-level CMakeLists.txt, we set CMAKE_BUILD_WITH_INSTALL_RPATH to ON,
and then for the unit tests we set it to <test>/../../lib. This works for tests
that live in unittest/<whatever>, but not for those that live in subdirectories
e.g. unittest/Transforms/IPO or unittest/ExecutionEngine/Orc. When building
with BUILD_SHARED_LIBRARIES, such tests don't manage to find their libraries.
Since the tests are run from the build directory, it makes sense to set their
RPATH for the build tree, rather than the install tree. This is the default in
CMake since 2.6, so all we have to do is set CMAKE_BUILD_WITH_INSTALL_RPATH to
OFF for the unit tests.

This commit modifies the memory buffer creation in the AsmParser library so
that it requires a terminating null character. The LLLexer in the AsmParser
library checks for EOF only when it sees a null character, thus it would
be best to require it when creating a memory buffer so that the memory
buffer constructor can verify that a terminating null character is indeed
present.

The llvm-level tests for coverage mapping need a binary input file,
which means they're hard to understand, hard to update, and it's
difficult to add new ones. By adding some unit tests that build up the
coverage data structures in C++, we can write more meaningful and
targeted tests.

*numerous* places where it was missing in the CMake build. The primary
change here is that the suffix is now actually used for all of the lib
directories in the LLVM project's CMake. The various subprojects still
need similar treatment.
This is the first of a series of commits to try to make LLVM's cmake
effective in a multilib Linux installation. I don't think many people
are seriously using this variable so I'm hoping the fallout will be
minimal. A somewhat unfortunate consequence of the nature of these
commits is that until I land all of them, they will in part make the
brokenness of our multilib support more apparant. At the end, things
should actually work.

This library will be used by clang-query. I can imagine LLDB becoming another
client of this library, so I think LLVM is a sensible place for it to live.
It wraps libedit, and adds tab completion support.
The code is loosely based on the line editor bits in LLDB, with a few
improvements:
- Polymorphism for retrieving the list of tab completions, based on
the concept pattern from the new pass manager.
- Tab completion doesn't corrupt terminal output if the input covers
multiple lines. Unfortunately this can only be done in a truly horrible
way, as far as I can tell. But since the alternative is to implement our
own line editor (which I don't think LLVM should be in the business of
doing, at least for now) I think it may be acceptable.
- Includes a fallback for the case where the user doesn't have libedit
installed.
Note that this uses C stdio, mainly because libedit also uses C stdio.

This patch fixes a small mistake in MCDataAtom::addData() where it doesn't ever
call remap():
- if (Data.size() > Begin - End - 1)
+ if (Data.size() > End + 1 - Begin)
remap(Begin, End + 1);
This is currently not visible because of another bug is the disassembler, so
the patch includes a unit test.

Makefiles, the CMake files in every other part of the LLVM tree, and
sanity.
This should also restore the output tree structure of all the unit
tests, sorry for breaking that, and thanks for letting me know.
The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages:
- No more weird directory stripping in the unittest macro, allowing it
to be used more readily in other projects.
- No more directory prefixes on all the source files.
- Allows correct and precise use of LLVM's per-directory dependency
system.
- Allows use of the checking logic for source files that have not been
added to the CMake build. This uncovered a file being skipped with
CMake in LLVM and one in Clang's unit tests.
- Makes Specifying conditional compilation or other custom logic for JIT
tests easier.
It did require adding the concept of an explicit 'optional' source file
to the CMake build so that the missing-file check can skip cases where
the file is *supposed* to be missing. =]
This is another chunk of refactoring the CMake build in order to make it
usable for other clients like CompilerRT / ASan / TSan.
Note that this is interdependent with a Clang CMake change.

facilities.
This was only used in one place in LLVM, and was used pervasively (but
with different code!) in Clang. It has no advantages over the standard
CMake facilities and in some cases disadvantages.

array of a suitable size and alignment for any of a number of different
types to be stored into the character array.
The mechanisms for producing an explicitly aligned type are fairly
complex because this operation is poorly supported on all compilers.
We've spent a fairly significant amount of time experimenting with
different implementations inside of Google, and the one using explicitly
expanded templates has been the most robust.
Credit goes to Nick Lewycky for writing the first 20 versions or so of
this logic we had inside of Google. I based this on the only one to
actually survive. In case anyone is worried, yes we are both explicitly
re-contributing and re-licensing it for LLVM. =]
Once the issues with actually specifying the alignment are finished, it
turns out that most compilers don't in turn align anything the way they
are instructed. Testing of this logic against both Clang and GCC
indicate that the alignment constraints are largely ignored by both
compilers! I've come up with and used a work-around by wrapping each
alignment-hinted type directly in a struct, and using that struct to
align the character array through a union. This elaborate hackery is
terrifying, but I've included testing that caught a terrifying number of
bugs in every other technique I've tried.
All of this in order to implement a poor C++98 programmers emulation of
C++11 unrestricted unions in classes such as SmallDenseMap.

For objects that can be identified by small unsigned keys, SparseSet
provides constant time clear() and fast deterministic iteration. Insert,
erase, and find operations are typically faster than hash tables.
SparseSet is useful for keeping information about physical registers,
virtual registers, or numbered basic blocks.

retain calls.

is testing the bitcode reader's functionality, not VMCore's. Add the
what is a hope sufficient build system mojo to build and run a new
unittest.
Also clean up some of the test's naming. The goal for the file should be
to unittest the Bitcode Reader, and this is just one particular test
among potentially many in the future. Also, reverse my position and
relegate the PR# to a comment, but stash the comment on the same line as
the test name so it doesn't get lost. This makes the code more
self-documenting hopefully w/o losing track of the PR number.
