Migrate dw2-ifort-parameter.exp to Dwarf::assemble
A "side effect" of the migration to Dwarf::assemble is that the DWARF address size is now automatically adjusted to the target architecture. The original assembler source hard-coded the DWARF address size to 4, even on 64-bit architectures. This address size mismatch caused a test case failure on s390x due to a wrong result from DW_OP_deref.
