1f8880558e Remove LLVM_INSTALL_CCTOOLS_SYMLINKS
It used to symlink dsymutil to llvm-dsymutil, but after r327790 llvm's dsymutil
binary is now called dsymutil without prefix.

r327792 then reversed the direction of the symlink if
LLVM_INSTALL_CCTOOLS_SYMLINKS was set, but that looks like a buildfix and not
like something anyone should need.

a595d2986a [dsymutil] Rename llvm-dsymutil -> dsymutil
Now that almost all functionality of Apple's dsymutil has been
upstreamed, the open source variant can be used as a drop in
replacement. Hence we feel it's no longer necessary to have the llvm
prefix.

8c60842d3a build: add the ability to create a symlink for dsymutil
Add a `LLVM_INSTALL_CCTOOLS_SYMLINKS` to mirror
`LLVM_INSTALL_BINUTILS_SYMLINKS`.  For now, this allows us to create
symlinks for `dsymutil` to `llvm-dsymutil`.  This option is off by
default, but the user can enable it.

8e98660f03 [tools] Add option to install binutils symlinks
The LLVM tools can be used as a replacement for binutils, in which case
it's convenient to create symlinks with the binutils names. Add support
for these symlinks in the build system. As with any other llvm tool
symlinks, the user can limit the installed symlinks by only adding the
desired ones to `LLVM_TOOLCHAIN_TOOLS`.

1b156543dd [cmake] Stop putting the revision info in LLVM_VERSION_STRING
Summary:
This reduces the number of build actions after a no-op commit from
thousands to about six, which should be acceptable. If six actions is
still too many, developers can disable the LLVM_APPEND_VC_REV cmake
option.

llvm-config.h is a widely included header that should rarely change.
Before this patch, it would change after every re-configure. Very few
users of llvm-config.h need to know the precise version, and those that
do can migrate to incorporating LLVM_REVISION as provided by
llvm/Support/VCSRevision.h.

This should bring LLVM back to the behavior that it had before r306858
from June 30 2017. Most LLVM tools will now print a version string like
"6.0.0svn" instead of "6.0.0-git-c40c2a23de4".

f87de988a8 [cmake] Add LLVM_ENABLE_DIA_SDK option, and expose it in LLVMConfig
Add an explicit LLVM_ENABLE_DIA_SDK option to control building support
for DIA SDK-based debugging. Control its value to match whether DIA SDK
support was found and expose it in LLVMConfig (alike LLVM_ENABLE_ZLIB).

Its value is needed for LLDB to determine whether to run tests requiring
DIA support. Currently it is obtained from llvm/Config/config.h;
however, this file is not available for standalone builds. Following
this change, LLDB will be modified to use the value from LLVMConfig.

d060d957a1 Add experimental support for unofficial monorepo-like directory layout
Summary:
This allows to have clang and llvm and the other subprojects
side-by-side instead of nested. This can be used with the monorepo or
multiple repos.

It will help having a single set of sources checked out but allows to
have a build directory with llvm and another one with llvm+clang.
Basically it abstracts LLVM_EXTERNAL_xxxx_SOURCE_DIR making it more
convenient by adopting a convention.

433a851091 [cmake] Support overriding remaining HTML doc install directories
Support overriding the Doxygen & OCamldoc install directories,
and provide a more FHS-compliant defaults for both of them. This extends
r282240 that added this override for Sphinx-built documentation.

LLVM_INSTALL_DOXYGEN_HTML_DIR and LLVM_INSTALL_OCAMLDOC_HTML_DIR are
added, to control the location where Doxygen-generated and
OCamldoc-generated HTML docs are installed appropriately. They both
specify CMake-style install paths, and therefore can either by relative
to the install prefix or absolute.

The new defaults are subdirectories of share/doc/llvm, and replace
the previous directories of 'docs/html' and 'docs/ocaml/html' that
resulted in creating invalid '/usr/docs' that furthermore lacked proper
namespacing for the LLVM package. The new defaults are consistent with
the ones used for Sphinx HTML documentation, differing only in the last
component. Since the 'html' subdirectory is already used for Sphinx
docs, the 'doxygen-html' and 'ocaml-html' directories are used instead.

616b6eef0d [CMake] Make LLVMConfig.cmake variable names match in-tree names
With the runtimes build we're trying to use LLVMConfig.cmake as a way of providing LLVM_* variables that are needed to behave as if the project is building in tree. To make this work we need to rename two variables by dropping the "S" from the end. This makes the variables match the in-tree names.

This renames:
LLVM_INCLUDE_DIRS -> LLVM_INCLUDE_DIR
LLVM_LIBRARY_DIRS -> LLVM_LIBRARY_DIR

The versions ending in S are not used in-tree anywhere. This also cleans up LLVM_LIBRARY_DIR being set to the same value with and without the "S".

195e842656 Add new LLVM_EXTERNAL_PROJECTS option to cmake
The new option makes it possible to build external projects as part of
the llvm build without copying (or symlinking) then into llvm/tool with
specifying a few additional cmake variables.

Example usage (2 additional project called foo and bar):
-DLLVM_EXTERNAL_PROJECTS="Foo;Bar"
-DLLVM_EXTERNAL_FOO_SOURCE_DIR=/src/foo
-DLLVM_EXTERNAL_BAR_SOURCE_DIR=/src/bar

Note: This is the extension of the approach we already support for
clang/lldb/poly with adding an option to specify additional supported
projects.

d429dd288c [ADT][CMake][AutoConf] Fail-fast iterators for DenseMap
Summary:
This patch is an attempt at making `DenseMapIterator`s "fail-fast".
Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)
on access, instead of non-deterministically hitting memory corruption
issues.

Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are
predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`.
`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /
autoconf build system.
