eliminate unimplemented vax and cray floating point formats
* mach-info.h (oct_mach_info::float_format): Delete flt_fmt_vaxd,
flt_fmt_vaxg, and flt_fmt_cray enum values.
* ls-mat4.cc (float_format_to_mopt_digit, mopt_digit_to_float_format):
Delete cases for vaxd, vaxg, and cray floating point formats.
* lo-ieee.cc (octave_ieee_init): Likewise.
* mach-info.cc (get_float_format,
oct_mach_info::string_to_float_format,
oct_mach_info::float_format_as_string): Likewise.
* oct-stream.cc: Delete explicit template instantiation for do_write.
(octave_stream::write, do_read): Delete checks for vaxd and vaxg
floating point formats.
* pr-output.cc (pr_any_float): Don't check for cray or unknonwn float
formats.
* data-conv.cc (VAX_D_double_to_IEEE_little_double,
VAX_G_double_to_IEEE_little_double, Cray_to_IEEE_little_double,
IEEE_big_float_to_IEEE_little_float, VAX_D_float_to_IEEE_little_float,
