XL: Consolidate compiler flag information Factor duplicate information out of Compiler/XL-<lang>.cmake modules into a macro in a new Compiler/XL.cmake module. Invoke it from the per-language files to produce the original settings.

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.

Split XL compiler information files This moves platform-independent XL compiler flags into separate "Compiler/XL-<lang>.cmake" modules. Platform-specific flags go in "Platform/<os>-XL-<lang>.cmake" modules.

Add initial XL C compiler flags for safer builds This commit adds some default initial C flags for the XL compiler. The most important is "-qhalt=e" which causes the compiler to error-out on non-severe error messages. This is necessary to get try-compiles to fail when bad arguments are passed to a function.

# -qthreaded = Ensures that all optimizations will be thread-safe
# -qhalt=e = Halt on error messages (rather than just severe errors)
