Print column information in RTL dumps

[Eric Botcazou]

Now that -gcolum-info is the default, I think that it makes sense to print the 
column info in the RTL dumps to be able to find out where numbers come from.

Tested on x86_64-suse-linux, applied on the mainline.

        * print-rtl.c (rtx_writer::print_rtx_operand_code_i): Print column
        information.

        * gcc.target/i386/vararg-loc.c: Accept a column number.
