target-arm: Give the FPSCR rounding modes names
When setting rounding modes we currently just hardcode the numeric values
for rounding modes in a big switch statement.
With AArch64 support coming, we will need to refer to these rounding modes
at different places throughout the code though, so let's better give them
names so we don't get confused by accident.
