    C-SKY: Add conditions for ceil etc patterns.
    
    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.
