Fix missing newlines from local-pure-const pass dump
I noticed the debugging output from local-pure-const pass is missing a
newline in a couple places, leading to this:
local analysis of main
scanning: i ={v} 0;
Volatile stmt is not const/pure
Volatile operand is not const/pure scanning: j ={v} 20;
Volatile stmt is not const/pure
Volatile operand is not const/pure scanning: vol.0_10 ={v} i;

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).

memory addresses (being ptr_mode rather than Pmode), so the assert
