rs6000: Another PIC LRA fix
This one for TARGET_TOC && TARGET_MINIMAL_TOC. Without it, r30 is not
saved in the prologue for functions that do not use r30, but the register
is set later in the prologue anyhow. This made all java tests fail.

* config/rs6000/rs6000.c (rs6000_reg_live_or_pic_offset_p): Use the
same condition for testing whether RS6000_PIC_OFFSET_TABLE_REGNUM is
live as for using it elsewhere, for TARGET_MINIMAL_TOC.
