gdb/fortran: Allow Flang MAIN_ in Fortran testing

Name of fortran main function for Flang compiler is MAIN_ while
for gfortran it is MAIN__ . In test cases MAIN__ is hardcoded for
the purpose of inserting breakpoint.

New proc is added to detect main function name depending on the
compiler used.
Fortran specific version of runto_main named fortran_runto_main
is added.

This commit adds support for Flang main function, there should be
no change for gfortran.
