The ceil etc functions can be only inlined as instruction when
they can raise the "inexact" exception. Without the adding
conditions, it will cause the "gcc.dg/torture/builtin-fp-int-inexact-c2x.c"
etc cases fails.

gcc/
	* config/csky/csky_insn_fpuv3.md (l<frm_pattern><fixsuop><mode>si2): Test
	flag_fp_int_builtin_inexact || !flag_trapping_math.
	(<frm_pattern><mode>2): Likewise.
