* gfortran.texi: Document the GFORTRAN_CONVERT_UNIT environment
variable.
* invoke.texi: Mention the "Runtime" chapter.
Document the -fconvert= option.
* gfortran.h: Add options_convert.
* lang.opt: Add fconvert=little-endian, fconvert=big-endian,
fconvert=native and fconvert=swap.
* trans-decl.c (top level): Add gfor_fndecl_set_convert.
(gfc_build_builtin_function_decls): Set gfor_fndecl_set_convert.
(gfc_generate_function_code): If -fconvert was specified,
and this is the main program, add a call to set_convert().
* options.c: Handle the -fconvert options.
