Hi,

Optimize signed DImode -> TImode on power10, PR target/104698.
On power10, GCC tries to optimize the signed conversion from DImode to
TImode by using the vextsd2q instruction. However to generate this
instruction, it would have to generate 3 direct moves (1 from the GPR
registers to the altivec r
