Similar to BCAX, we can use EOR3 for DImode, but we have to be careful
not to force GP<->SIMD moves unnecessarily, so add a splitter for that case.
So for input:
uint64_t eor3_d_gp (uint64_t a, uint64_t b, uint64_t c) { return EOR3 (a, b, c); }
uint64x1_t eor3_d (uint64x1_t a, uint64x1_t b, uint64x1_t c) { return EOR3 (a, b, c); }
We generate the desired:
eor3_d_gp:
eor x1, x1, x2
eor x0, x1, x0
ret
eor3_d:
eor3 v0.16b, v0.16b, v1.16b, v2.16b
ret
Bootstrapped and tested on aarch64-none-linux-gnu.
