Víctor Colombo c3f24257e3 target/ppc: Clear fpstatus flags on helpers missing it 
In ppc emulation, exception flags are not cleared at the end of an
instruction. Instead, the next instruction is responsible to clear
it before its emulation. However, some helpers are not doing it,
causing an issue where the previously set exception flags are being
used and leading to incorrect values being set in FPSCR.
Fix this by clearing fp_status before doing the instruction 'real' work
for the following helpers that were missing this behavior:

- VSX_CVT_INT_TO_FP_VECTOR
- VSX_CVT_FP_TO_FP
- VSX_CVT_FP_TO_INT_VECTOR
- VSX_CVT_FP_TO_INT2
- VSX_CVT_FP_TO_INT
- VSX_CVT_FP_TO_FP_HP
- VSX_CVT_FP_TO_FP_VECTOR
- VSX_CMP
- VSX_ROUND
- xscvqpdp
- xscvdpsp[n]
