Subject: Support {CEIL,FLOOR,ROUND}_{DIV,MOD}_EXPR and EXACT_DIV_EXPR in
 GIMPLE FE

The following adds support for the various division and modulo operators
to the GIMPLE frontend via __{CEIL,FLOOR,ROUND}_{DIV,MOD} and
__EXACT_DIV operators.

gcc/c/
	* gimple-parser.cc (c_parser_gimple_binary_expression):
	Parse __{CEIL,FLOOR,ROUND}_{DIV,MOD} and __EXACT_DIV.

gcc/testsuite/
	* gcc.dg/gimplefe-53.c: New testcase.
