S/390: Get rid of Y constraint in rotate patterns.
This patch introduces substitution patterns to add PLUS const_int, and
AND operands to patterns and uses this to rewrite the existing rotate
pattern.
gcc/ChangeLog:

S/390: Use enabled attribute overrides to disable
alternatives.
So far whenever we wanted to disable an alternative we have used mode
attributes emitting constraints matching an earlier alternative
assuming that due to this the later alternative will never be chosen.
With this patch the `enabled' attribute, which so far is only set from
`cpu_facility', is overridden to 0 to disable certain alternatives.
This comes handy when defining the substitutions later and while
adding it anyway I've used it for the existing cases as well.

gensupport: Fix define_subst operand renumbering.
When processing substitutions the operands are renumbered. To find a
free operand number the array used_operands_numbers is used.
Currently this array is used to assign new numbers before all the
RTXes in the vector have been processed. I did run into problems with
this for insns where a match_dup occurred in a later (use ...) operand
referring to an earlier operand (e.g. s390.md "setmem_long").
The patch splits the loop doing the processing into two in order to
have all the operand numbers collected already when assigning new
numbers.

powerpc: Handle DImode rotatert implemented with rlwinm (PR69946)
Some DImode rotate-right-and-mask can be implemented best with a rlwinm
instruction: those that could be a lshiftrt instead of a rotatert, while
the mask is not right-aligned. Why the rotate in the testcase is not
optimised to a plain shift is another question, but we need to handle
it here anyway. We compute the shift amount for a 64-bit rotate. This
is 32 too high in this case; if we print using %h that is masked out (and
this doesn't silently let through invalid instructions, everything is
checked by rs6000_is_valid_shift_mask which is much more thorough).

The target operand is used as temporary. This fails if it matches the
