NAKAMURA Takumi 1aa7442231 Provide CMake package modules in install tree
Teach the Makefile build system to generate and install CMake modules
LLVMConfig.cmake and LLVMConfigVersion.cmake so that applications that
build with CMake can use 'find_package(LLVM)' even when LLVM is not
built with CMake.  These modules tell such applications about available
LLVM libraries and their dependencies.

Run llvm-config to generate the list of libraries and use the results of
llvm-build to generate the library dependencies.  Use sed to perform
substitutions in the LLVMConfig.cmake.in and LLVMConfigVersion.cmake.in
sources that our CMake build system uses.

Teach the Makefile build system to generate the LLVMExports.cmake file
with content similar to that produced by the CMake install(EXPORT)
command.  Extend llvm-build with an option to generate the library
dependencies fragment for this file.

# Top-Level LLVM Build Stages:
# 1. Build lib/Support and lib/TableGen, which are used by utils (tblgen).
# 2. Build utils, which is used by IR.
# 3. Build IR, which builds the Intrinsics.inc file used by libs.
# 4. Build libs, which are needed by llvm-config.
# 5. Build llvm-config, which determines inter-lib dependencies for tools.
# 6. Build tools, docs, and cmake modules.
#
# When cross-compiling, there are some things (tablegen) that need to
# be build for the build system first.
# If "RC_ProjectName" exists in the environment, and its value is

# "Apple-style" in the comments for more info. Anything else is a
# normal build.
