Fix riscv_expand_conditional_move.
Two issues have been observed in current riscv_expand_conditional_move
implementation.
1. Before introduction of TARGET_XTHEADCONDMOV, op0 of comparision
expression
is used for mode comparision with word_mode, but after TARGET_XTHEADCONDMOV
megered with TARGET_SFB_ALU, dest of if-then-else is used for mode
comparision with
word_mode, and from md file mode of dest is DI or SI which can be different
with
word_mode in RV64.
2. TARGET_XTHEADCONDMOV cannot be generated when the mode of the comparison
is E_VOID.
