CheckFortranCompilerFlag: Add module to check Fortran flag existence
Copy the CheckCCompilerFlag module and replace 'C' with 'Fortran'. Also update the common patterns module to match some Fortran compiler messages.

+# CheckFortranCompilerFlag
+# ------------------------
+#
+# Check whether the Fortran compiler supports a given flag.
+#
+# CHECK_Fortran_COMPILER_FLAG(<flag> <var>)
+#
+# ::
+#
+# <flag> - the compiler flag
+# <var> - variable to store the result
+# Will be created as an internal cache variable.
+#
+# This internally calls the check_fortran_source_compiles macro and
+# sets CMAKE_REQUIRED_DEFINITIONS to <flag>. See help for
+# CheckFortranSourceCompiles for a listing of variables that can
+# otherwise modify the build. The result only tells that the compiler
+# does not give an error message when it encounters the flag. If the
+# flag has any effect or even a specific one is beyond the scope of
+# this module.
