Rafael Espindola 8d6b63c39e llvm-readobj: use the associated string table to print symbols. NFI.
This just removes some cases that require ELFFile to eagerly parse the ELF

Chris Bieneman 19d42692e7 [CMake] Projects supported via LLVM_EXTERNAL_*_SOURCE_DIR need to be explicitly specified.
One part of my refactoring from r242705 is untenable due to how CMake caches variables. There is no way other than caching to allow variables to be set in one directory and globally readable, but we really don't want to cache the temporary value marking that a directory has already been included.

Chris Bieneman 580d8159d5 [CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.
Re-landing r242059 which re-landed r241621... I'm really bad at this.

Summary (r242059):
This change re-lands r241621, with an additional fix that was required to allow tool sources to live outside the llvm checkout. It also no longer renames LLVM_EXTERNAL_*_SOURCE_DIR. This change was reverted in r241663, because it renamed several variables of the format LLVM_EXTERNAL_*_* to LLVM_TOOL_*_*.

Summary (r241621):
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:

* factored out canonicalizing tool names from paths to CMake variables * removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

Rafael Espindola 4b83cb5390 Add support for reading members out of thin archives.
For now the Archive owns the buffers of the thin archive members.
This makes for a simple API, but all the buffers are destructed
only when the archive is destructed. This should be fine since we
close the files after mmap so we should not hit an open file
limit.

JF Bastien 704dc4b004 Fix `llvm-config` to emit the linker flag for the combined shared object built by autoconfig/make instead of the individual components.
Summary:
This fixes `llvm-config` instead of fixing the makefiles because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.

This change only affects builds that use autoconfig/make.
