Don't copy regs that are only used in the entry block into a vreg. This
changes the code generated for:
short %test(short %A) {
%B = xor short %A, -32768
ret short %B
}
to:
_test:
xori r2, r3, 32768
xoris r2, r2, 65535
extsh r3, r2
blr
instead of:
_test:
rlwinm r2, r3, 0, 16, 31
xori r2, r3, 32768
xoris r2, r2, 65535
extsh r3, r2
blr
