Pirama Arumuga Nainar 7476bc89e9 Don't combine fp_round (fp_round x) if f80 to f16 is generated ... Summary: This patch skips DAG combine of fp_round (fp_round x) if it results in an fp_round from f80 to f16. fp_round from f80 to f16 always generates an expensive (and as yet, unimplemented) libcall to __truncxfhf2. This prevents selection of native f16 conversion instructions from f32 or f64. Moreover, the first (value-preserving) fp_round from f80 to either f32 or f64 may become a NOP in platforms like x86.
