Fix dw2-ifort-parameter.exp on PPC64
On PPC64, 'func' and 'main' are function descriptors and don't point to the actual code. Thus the usage of these symbols in the DWARF assembler source was broken. The patch introduces new labels func_start and func_end for this purpose.

* gdb.dwarf2/dw2-ifort-parameter-debug.S: Remove.
* gdb.dwarf2/dw2-ifort-parameter.exp: Use Dwarf::assemble to
generate the debug info assembler source.
