[flang] Catch more initialization errors
Diagnose some error cases related to initialization that are
slipping past semantic checking: don't allow multiple initializations
of the same symbol, and don't allow an object that was initialized
as a scalar to become an array afterward.
Fixes llvm-test-suite/Fortran/gfortran/regression/initialization_17.f90.
