C-SKY: Add conditions for ceil etc patterns.

Browse Source 
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.
