[PATCH] target/loongarch: Fix "movfcsr2gr" gets wrong value

[Qi Hu]

In follow sequence:
  movgr2fcsr $r0,$r0
  movgr2fr.d $f0,$r0
  fdiv.d     $f0,$f0,$f0
  movfcsr2gr $r12,$r0

The value of $r12 is "0x00000000", but it should be "0x10100000"(V flag).

These fp helpers are definded with wrong flag "TCG_CALL_NO_WG" (but the
helpers write the globle "fcsr"). This causes the "fdiv" helper updates
the "fcsr" into mem, but "movfcsr2gr" does not load it from mem.
