convert.c (convert_to_integer): Convert (long int)trunc{,f,l}, and (long long int)ceil{,f,l} into FIX_TRUNC_EXPR.

	* convert.c (convert_to_integer): Convert (long int)trunc{,f,l},
	and (long long int)ceil{,f,l} into FIX_TRUNC_EXPR.

testsuite:

	* gcc.dg/builtins-53.c: Also check (int)trunc* and
	(long long int)trunc*.
