LLVMConfig.cmake file that is (I think) used in the stand-alone Clang
build, and causing link errors there w.r.t. curses.

using it to detect whether or not a terminal supports colors. This
replaces a particularly egregious hack that merely compared the TERM
environment variable to "dumb". That doesn't really translate to
a reasonable experience for users that have actually ensured their
terminal's capabilities are accurately reflected.

This makes testing a terminal for color support somewhat more expensive,
but it is called very rarely anyways. The important fast path when the
output is being piped somewhere is already in place.

The global lock may seem excessive, but the spec for calling into curses
is *terrible*. The whole library is terrible, and I spent quite a bit of
time looking for a better way of doing this before convincing myself
that this was the fundamentally correct way to behave. The damage of the
curses library is very narrowly confined, and we continue to use raw
escape codes for actually manipulating the colors which is a much sane
system than directly using curses here (IMO).

If this causes trouble for folks, please let me know. I've tested it on
Linux and will watch the bots carefully. I've also worked to account for
the variances of curses interfaces that I could finde documentation for,
but that may not have been sufficient.

Previously this check was guarded by MSVC, which doesn't distinguish
between the compiler and the headers/library.  This enables clang to
compile more of LLVM on Windows with Microsoft headers.

Remove some unused macros while I'm here: error_t and LTDL stuff.

Replacing /GR with /GR- instead of applying both options to the project.  This should reduce some build bot warnings (D9025: "overriding '/GR' with '/GR-'").

On Windows, this improves clean cmake configuration time on my
workstation from 1m58s to 1m32s, which is pretty significant.  There's
probably more that can be done here, but this is the low hanging fruit.

Eric volunteered to regenerate ./configure for me.

The issue is that CMAKE_BUILD_TYPE=RelWithDebInfo LLVM_ENABLE_ASSERTIONS=ON was
not building with assertions enabled.  (I was unable to find what in the LLVM
source tree was adding -DNDEBUG to the build line in this case, so decided that
it must be cmake itself that was adding it - this may depend on the cmake
version).  The fix treats any mode that is not Debug as being the same as
Release for this purpose (previously it was being assumed that cmake would only
add -DNDEBUG for Release and not for RelWithDebInfo or MinSizeRel).  If other
versions of cmake don't add -DNDEBUG for RelWithDebInfo then that's OK: with
this change you just get a useless but harmless -UNDEBUG or -DNDEBUG.

[SystemZ] Add configure bits

This patch wires up the SystemZ target in configure, so that it can now be
built using --enable-targets=systemz.   It is not yet included in the default
build (--enable-targets=all); this will be done by a follow-up patch.

The intended semantics mirror autoconf, where the user is able to
specify a host triple, but if it's left to the build system then
"config.guess" is invoked for the default.

This also renames the LLVM_HOSTTRIPLE define to LLVM_HOST_TRIPLE to
fit in with the style of the surrounding defines.
