After 8367c996e55b2 commit several checks on round_32.c test started to

The reason is that we prevent rounding DF->SI->DF on RV32 and instead of
a conversation sequence we get calls to appropriate library functions.
gcc/testsuite/ChangeLog:
* testsuite/gcc.target/riscv/round_32.c: Fixed test
I wonder if this test even makes sense for rv32 anymore given we can't
do a DF->DI as a single instruction and DF->SI is going to give
incorrect results. So the underlying optimization to improve those
rounding cases just doesn't apply to DF mode objects for rv32.
Thoughts?
