Getting rid of the name "optimization remarks" for anything that
involves handling remarks on the client side.
It's safer to do this now, before we get stuck with that name in all the
APIs and public interfaces we decide to export to users in the future.
This renames llvm/tools/opt-remarks to llvm/tools/remarks-shlib, and now
generates `libRemarks.dylib` instead of `libOptRemarks.dylib`.

TextAPI is a library and accompanying tool that allows conversion between binary shared object stubs and textual counterparts. The motivations and uses cases for this are explained thoroughly in the llvm-dev proposal [1]. This initial commit proposes a potential structure for the TAPI library, also including support for reading/writing text-based ELF stubs (.tbe) in addition to preliminary support for reading binary ELF files. The goal for this patch is to ensure the project architecture appropriately welcomes integration of Mach-O stubbing from Apple's TAPI [2].
Added:
- TextAPI library
- .tbe read support
- .tbe write (to raw_ostream) support

Add a library that parses optimization remarks (currently YAML, so based
on the YAMLParser).
The goal is to be able to provide tools a remark parser that is not
completely dependent on YAML, in case we decide to change the format
later.
It exposes a C API which takes a handler that is called with the remark
structure.
It adds a libLLVMOptRemark.a static library, and it's used in-tree by
the llvm-opt-report tool (from which the parser has been mostly moved
out).

Fixed the tests by removing the usage of C++11 strings, which seems not

Summary:
Add a new plugin API. This closes the gap between pass registration and out-of-tree passes for the new PassManager.
Unlike with the existing API, interaction with a plugin is always
initiated from the tools perspective. I.e., when a plugin is loaded, it
resolves and calls a well-known symbol `llvmGetPassPluginInfo` to obtain
details about the plugin. The fundamental motivation is to get rid of as
many global constructors as possible. The API exposed by the plugin
info is kept intentionally minimal.

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.
