eric fang d25476ebb2 cmd/internal/obj/arm64: fix constant pool size calculation error
The current calculation method of constant pool size is:
  c.pool.size = -c.pool.size & (funcAlign - 1)
  c.pool.size += uint32(sz)
This doesn't make sense. This CL changes it as:
  if q.As == ADWORD {
    c.pool.size = roundUp(c.pool.size, 8)
  }
  c.pool.size += uint32(sz)
which takes into account the padding size generated by aligning DWORD to
8 bytes.

It's unnecessary to set the Pc field in addpool and addpool128 because
the Pc value will be reset in function span7, so remove the related lines.
