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.

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)
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. Suggested-by: Todd Gamblin <tgamblin@llnl.gov>
