RISC-V: Fix ICE for incorrect mode attr in V_F2DI_CONVERT_BRIDGE
The mode attr V_F2DI_CONVERT_BRIDGE converts the floating-point mode to the widden floating-point by design. But we take (RVVM1HF "RVVM2SI") by mistake. This patch would like to fix it by replacing the (RVVM1HF "RVVM2SI") to (RVVM1HF "RVVM2SF") as design. gcc/ChangeLog: * config/riscv/vector-iterators.md: Replace RVVM2SI to RVVM2SF for mode attr V_F2DI_CONVERT_BRIDGE. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/unop/math-lroundf16-rv64-ice-1.c: New test.
