[Ada] Add stream-oriented attributes support for 128-bit integer types
gcc/ada/
* doc/gnat_ugn/building_executable_programs_with_gnat.rst (-xdr):
Document that XDR is not supported for 128-bit integer types.
* gnat_ugn.texi: Regenerate.
* exp_strm.adb (Build_Elementary_Input_Call): Deal with types
larger than Long_Long_Integer.
(Build_Elementary_Write_Call): Likewise.
* rtsfind.ads (RE_Id): Add RE_I_LLL{I,U] and RE_W_LLL{I,U}.
(RE_Unit_Table): Add entries for them.
* libgnat/s-stratt.ads (I_LLLI): New inline function.
(I_LLLU): Likewise.
(W_LLLI): New inline procedure.
(W_LLLU): Likewise.
* libgnat/s-stratt.adb (S_LLLI): New subtype of SEA.
(S_LLLU): Likewise.
(From_LLLI): New instance of Unchecked_Conversion.
(From_LLLU): Likewise.
(To_LLLI): Likewise.
(To_LLLU): Likewise.
(I_LLLI): Implement.
(I_LLLU): Likewise.
(W_LLLI): Likewise.
(W_LLLU): Likewise.
