rs6000: Fix rs6000_emit_le_vsx_store (PR98549)
One of the advantages of LRA is that you can create new pseudos from it
just fine. The code in rs6000_emit_le_vsx_store was not aware of this.
This patch changes that, in the process fixing PR98549 (where it is
shown that we do call rs6000_emit_le_vsx_store during LRA, which we
used to assert can not happen).

* config/rs6000/rs6000.c (rs6000_emit_le_vsx_store): Change assert.
Adjust comment. Simplify code.
