Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly
dereference or quote the variable. We want if() to auto-dereference the
variable and not its value. Also replace MATCHES with STREQUAL where
equivalent.
Some compilers, such as Clang on OS X, do not want the -g flag for both
generating assembly code and assembling it. Drop the -g flag from
generation of main.s in the Assembler test.
Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.
On OS X if the user-provided flags do not include -isysroot and
CMAKE_OSX_SYSROOT is defined then add the proper -isysroot flag to the C
compiler invocation we use to generate the .s file.
Since commit 571dc748 (Recognize Clang C and C++ compilers, 2010-05-17)
we recognize Clang C and C++ support. Add Compiler/Clang-ASM.cmake to
enable use of Clang for ASM too. Also teach Assembler test to try Clang
as an assembler.

Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
Use a custom command to generate the assembly source file at build time.
Also set CMAKE_VERBOSE_MAKEFILE so the test output contains all the
build rules. These two changes will show the entire .c -> .s -> .o and
final link commands in the test output.
Commit 1f6c6b1c (use CMAKE_C_FLAGS when generating the assembler file,
2011-03-03) added use of CMAKE_C_FLAGS to the assembler generation step.
However, this variable is meant for direct substitution into a shell
command line so we need to parse it to separate the arguments first.
