optional library support to the llvm-build tool:
- Add new command line parameter to llvm-build: “--enable-optional-libraries”
- Add handing of new llvm-build library type “OptionalLibrary”
- Update Cmake and automake build systems to pass correct flags to llvm-build
based on configuration

llvm-ld is no longer useful and causes confusion and so it is being removed.
* Does not work very well on Windows because it must call a gcc like driver to
assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
ld, or fully replaced by Clang.
I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

- On OS X 10.7+ this is apparently recommended practice. This maybe should
become a configurey thing one day, but I'm not sure it is right to
automatically turn it on.

Clang builds. The detection logic for compilers that support the warning
isn't working. Rafael is going to investigate it, but didn't want people
to have to wade through build spam until then.

This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.
We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).
IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

Original commit message:
llvm-config: Replace with C++ version (was llvm-config-2).
- Reapply of r144300, with lots of fixes/migration easement in between.

Some files installed by clang are not relevant for general users and we'd like
to be able to install them to a different location. This adds a new
--with-internal-prefix configure option and a corresponding PROJ_internal_prefix
makefile variable, which defaults to the standard prefix. A tool makefile
can specify that it should be installed to this internal prefix by defining
INTERNAL_TOOL.

TARGETS_TO_BUILD variables to build tools submake, and also tweak echo command
to indicate when we are compiling/etc build tools.

some more of the explicit dependencies. I'm staging things more slowly this time
in case there is more unanticipated fallout.

to delete core files. This causes a warning in clang/lib/StaticAnalyzer on
case insensitive filesystems, since it contains a "Core" directory. Since this
is pointless anyway, just zap it.

- Basically, we coordinate with llvm-build to create a Makefile fragment we can
easily use. For now, nothing is wired in except the support to automatically
regenerate this file when necessary.

This allows the (many) pseudo-instructions we have that map onto a single
real instruction to have their expansion during MC lowering handled
automatically instead of the current cumbersome manual expansion required.
These sorts of pseudos are common when an instruction is used in situations
that require different MachineInstr flags (isTerminator, isBranch, et. al.)
than the generic instruction description has. For example, using a move
to the PC to implement a branch.

target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.
First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

config.cache will be used by the person who specifies '-C' to configure.
config.cache's inconsistency should be responsible to him.
Re-configuration would spend so much on cygming without '-C', esp. cygwin.
