Add platform variables for position independent code flags
Store in new platform variables CMAKE_${lang}_COMPILE_OPTIONS_PIC CMAKE_${lang}_COMPILE_OPTIONS_PIE flags for position independent code generation. In almost all cases, this means duplication of the CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the assumed pie equivalent for the _PIE case. Note that the GNU compiler has supported -fPIE since 3.4 and that there is no -fPIC on GNU for Windows or Cygwin. There is a possibility that the _PIE variables are not correct. However, as there is no backwards compatibility to be concerned about (as the POSITION_INDEPENDENT_CODE property is not used anywhere yet), the current state suffices.
