    gdb, fortran: Fix quad floating-point type for ifort compiler.
    
    I fixed this a while ago for ifx, one of the two Intel compilers, in
    8d624a9d8050ca96e154215c7858ac5c2d8b0b19.
    
    Apparently I missed that the older ifort Intel compiler actually emits
    slightly different debug info again:
    
    0x0000007a:   DW_TAG_base_type
                    DW_AT_byte_size (0x20)
                    DW_AT_encoding  (DW_ATE_complex_float)
                    DW_AT_name      ("COMPLEX(16)")
    
    0x00000081:   DW_TAG_base_type
                    DW_AT_byte_size (0x10)
                    DW_AT_encoding  (DW_ATE_float)
                    DW_AT_name      ("REAL(16)")
    
    This fixes two failures in gdb.fortran/complex.exp with ifort.
