Brad King a66004bee0 Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files 
Document these variables.

Change our convention for setting these variables from:

    set(CMAKE_C_FLAGS_INIT "...")

to

    string(APPEND CMAKE_C_FLAGS_INIT " ...")

so that any value previously set by a toolchain file will be used.

Automate the conversion with:

    sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
      Modules/Compiler/*.cmake Modules/Platform/*.cmake

and follow up with some manual fixes (e.g. to cases that already
meant to append).  Also revert the automated changes to contexts
that are not protected from running multiple times.

Brad King a33fb493de XL: Drop -qalias=noansi from default C flags 
This was added without explanation by commit v2.8.2~1138 (Add initial XL
C compiler flags for safer builds, 2009-09-30).  It is not consistent
with our default C++ flags for XL and disables several optimizations, so
drop it from our default flags for C.

Clinton Stimpson 0ddfc51f6a Add -DNDEBUG to RelWithDebInfo flags where where Release flags had it. 
Previously, it was inconsistent in that some platforms/compilers
had this flag for the RelWithDebInfo configuration and some didn't.
This fixes issue #11366.

Kitware Robot 77543bde41 Convert CMake-language commands to lower case 
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
