After Y is never used anymore with SImode operands we can finally
disallow SImode (if != Pmode) in s390_decompose_address.  In fact that
was the whole point of the patch series.

From-SVN: r233849

While trying to get rid of the Y constraint in the setmem patterns I
noticed that for these patterns it isn't even a problem since these
always only use the constraint with a Pmode match_operand.  But while
being at it I've tried to fold some of the patterns a bit.

This removes the Y constraint from the tabort pattern definition.  In

 patterns.

The arithmetic shift patterns set also the condition code.  This adds
more substitution potential.  Depending on whether the actual result
or the CC output will be used 3 different variants of each of these
patterns are needed.  This multiplied with the PLUS and the AND
operands from the earlier substitutions enables a lot of folding.

 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.

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.
