Bug#58871: Reorganize maintainer mode compiler flags to allow

           option for specific compilers

Reorganize the maintainer mode cmake code to allow options
for specific compilers. For now, enable -Wcheck for ICC,
but do not turn warnings into errors.

CMakeLists.txt:
  Move the code that sets options to cmake/maintainer.cmake
cmake/maintainer.cmake:
  Add macros for each specific compiler.
