PR10257: Add support for sprint[ln](@hist_*).

* parse.cxx (parser::parse_symbol): Add sprint[ln] to @hist_* hack.
* runtime/stat-common.c: Replace reprint with new reprint_buf, add more
  generic _stp_stat_print_histogram_buf and call it from the older one.
  Also correct some formatting issues.
* translate.cxx (c_unparser::visit_print_format): Add sprint case.
