* coff-alpha.c (reloc_nil): New function. 

(alpha_howto_table): Use it as special_function to prevent certain relocs from
being adjusted by bfd_perform_relocation.  IGNORE reloc should be
partial_inplace.
(alpha_ecoff_get_relocated_section_contents): Accept a LITERAL reloc on an
"ldl" instruction too.
