rs6000: Fix *movsi_from_df (PR88892)
The memory store instructions (stfs[u][x], stxssp[x]) can result in
garbage if the value to be stored isn't already a valid single
precision floating point number. So we cannot use this here.
PR target/88892
* config/rs6000/rs6000.md (*movsi_from_df): Allow only register
operands.
