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.

CMake and autotools disagree on what "host" means in a cross-compilation
context. Autotools (and lit) take it to be the machine the binaries being
compiled now will run on. CMake takes it to be the machine actually compiling
the binaries now.

This change makes lit.site-cfg more consistent between autotools and CMake,
allowing lit tests (particularly in ExecutionEngine) to run correctly when
cross-compiled with CMake

check_cxx_symbol_exists requires CMake 2.8.6, so even though I
recommended it to Owen it's probably better to stay away for now.
This check is not technically correct because we're checking <math.h>
but then using <cmath> in the actual code, but if we run into problems we
can do the same sort of dance as isinf() and isnan() where we check /both/
headers and then write a wrapper header around them.

Added support to the cmake build to turn off uninitialized use warnings
for gcc. This cleans the build up somewhat.

Used logic simpler than found in autoconf by making use of the fact that
although gcc won't complain about unsupported -Wno-* flags it *will*
complain about unsupported -W flags.

catches uses of an extremely minor and widely-available C++ extension (which
every C++ compiler I could find supports, but EDG and Clang reject in strict
mode).

The diagnosed code pattern looks like this:

struct X {
  union {
    struct {
      int a;
      int b;
    } S;

gcc produces false positives for empty braces so turning the warning off.
Instead, turning the warning on for clang so proper warnings aren't missed.

RUNTIME_BUILD_MODE can be substituted to CMAKE_CFG_INTDIR.

With Make and Ninja, the tree is not built with multiple configurations.
Then, including the build type in target directory doesn't make sense.
See also "How can I build multiple modes without switching?"
http://www.cmake.org/Wiki/CMake_FAQ
CMAKE_CFG_INTDIR is set to "."

With multiple-configuration-aware build system, like Visual Studio, each unittest is built on appropriate directory, for example,
unittests/ADT/Release/ADTTests.exe
CMAKE_CFG_INTDIR is set to build system's variable, like "$(Configuration)" or "$(OutDir)".

Thus, "--param build_config" is also deprecated.
