lra: Clobbers in a parallel are earlyclobbers (PR83245)

The documentation (rtl.texi) says:

  When a @code{clobber} expression for a register appears inside a
  @code{parallel} with other side effects, the register allocator
  guarantees that the register is unoccupied both before and after that
  insn if it is a hard register clobber.

and at least the rs6000 backend relies on that (see PR83245).  This
patch restores that behaviour.

Registers that are also used as operands in the instruction are not
treated as earlyclobber, so such insns also still work (PR80818, an
s390 testcase).

combine: Print to dump if some insn cannot be combined into i3

combine: Do not throw away unneeded arms of parallels (PR83156)

The fix for PR82621 makes us not split an I2 if one of the results of
those SETs is unused, since combine does not handle that properly.  But
this results in degradation for i386 (or more in general, for any
target that does not have patterns for parallels with an unused result
as a CLOBBER instead of a SET for that result).

This patch instead makes us not split only if one of the results is set
again before I3.  That fixes PR83156 and also fixes PR82621.

Unfortunately it undoes the nice optimisations that the previous patch
did on powerpc.

third operand.  It would be ideal if RTL was always canonicalised like
