to have them appear in the right order. Instead append all warnings explicitly
to the language flags. This was already the case for many warnings. Fixes the
issue of -Wno-maybe-uninitialized not being effective because -Wall was being
placed after it rather than before.

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.

For example,
cur) unittests/ADT/Release/ADTTests
new) unittests/ADT/ADTTests
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.

This warning fires on:
Operator::~Operator() {
llvm_unreachable("should never destroy an Operator");
}
That seems like a false positive. I don't see any good way to silence
the warning here, so I'm disabling it.

Adding CXX_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG
C_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG
This is to handle the wackiness on a Mac host where cmake detects:
CMAKE_CXX_COMPILER == "/usr/bin/c++"
CMAKE_C_COMPILER == "/usr/bin/gcc"

This was previously only done for executables and shared libraries, but not
for modules. As modules are essentially shared libraries (that need to be
dlopened explicitly), threating them the same as shared libraries seems
reasonable. This fixes the LLVM_BUILD_32_BITS build of Polly.

output. Peter Collingbourne also reports that it is showing up in
$(llvm-config --cflags).
Revert this for now since I don't know enough cmake to fix it properly.
This reverts commit 18efed7adc79c1970f307bb5b015d199012ba872.

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.

Take #2. Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.

--c(xx)flags' doesn't tell the absolute truth.
This comes from PR9603 and is based on a patch by Ryuta Suzuki!

Installs tblgen (required by Clang).
Translates handling of user settings and platform-dependant options to
its own file, where it can included by another project.
Installs the .cmake files required by projects like Clang.
