4008e3e5d7 [flang] Make include guards consistent. 
The include guard symbol is `FORTRAN_$dir_$file_H_` where $dir is the
subdirectory of `lib` and $file is the basename of the header file.
Those names are mapped to uppercase and hyphens are replaced by
underscores.

and also in converting statement functions to array element assignments.

resolve-names.cc:
Recognize references to functions and subroutines and add symbols for them.
Detect declaration conflicts from these and check `IMPLICIT NONE(EXTERNAL)`.

rewrite-parse-tree.cc:
Find function references that need to be converted and rewrite them.
