[CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.

Summary:
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

This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.

This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

SelectionDAG itself is not invoking directly the DataLayout in the
TargetMachine, but the "TargetLowering" class is still using it. I'll
address it in a following commit.

This change is part of a series of commits dedicated to have a single
DataLayout during compilation by using always the one owned by the
module.

This commit modifies the interface for the machine instruction parsing
functions by wrapping the parameter 'MBBSlots' in a new structure called
'PerFunctionMIParsingState'. This change is useful as in the future I will be
able to pass new parameters to the machine instruction parser just by modifying
the 'PerFunctionMIParsingState' structure instead of adding a new parameter to
each function.

getSymbolValue now returns a value that in convenient for most callers:
* 0 for undefined
* symbol size for common symbols
* offset/address for symbols the rest

Code that needs something more specific can check getSymbolFlags.

of the build stages that are sent through a pipe (e.g. tee) failed.

This potentially allowed builds and/or tests to fail without anyone
noticing. It appears that for the LLVM 3.6.[01] releases this actually
happened for the Ubuntu 14.04LTS binary releases. The essence of the
issue is that without ``set -o pipefail`` the following command in bash
has a zero exit code.

false | tee /dev/null ; exit $?

This type of prologue isn't supported yet. Implementing it should be a
matter of copying the adjusted incoming EBP into ESI (the base pointer)
instead of EBP.  The original EBP can be saved and restored from other

At least not in the interface exposed by ObjectFile. This matches what ELF and
COFF implement.

Adjust existing code that was expecting them to have values. No overall
functionality change intended.

Another option would be to change the interface and the ELF and COFF
implementations to say that the value of a common symbol is its size.
