Brad King 83957d9e0d Fix CHECK_(C|CXX)_COMPILER_FLAG for XL and SunPro
These compilers warn and return 0 for unrecognized flags.  We fix the
compiler flag check macros by looking for a warning in the output.  We
also update the regex for GNU on older Macs.  See issue #9516.

Brad King 80af3ae35d Cleanup generic compiler check macro documentation
This commit improves formatting and style of the documentation for the
general-purpose compiler check macros:

  CHECK_C_COMPILER_FLAG
  CHECK_C_SOURCE_COMPILES
  CHECK_C_SOURCE_RUNS
  CHECK_CXX_COMPILER_FLAG
  CHECK_CXX_SOURCE_COMPILES
  CHECK_CXX_SOURCE_RUNS

This sytle is more consistent with CMake command documentation.
It also looks nicer in the generated documentation text files.
