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.

   - Another reapply of r144300, with hopefully one last fix.

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.

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.

If enabled, this will attempt to use the CC_LOG_DIAGNOSTICS feature I dropped
into Clang to print a log of all the diagnostics generated during an individual
build (from the top-level). Not sure if this will actually be useful, but for
now it is handy for testing the option.

LLVMCC_EMITIR_FLAG is already either -emit-llvm or -fplugin-arg-dragonegg-emit-ir, so don't add an extra leading -.  Clang doesn't accept --emit-llvm.
