  tcg-s390: Use more risbg in the tlb sequence

Elides two insns from the sequence.  The resulting tlb compare
sequence is satisfyingly minimal:

        risbg  %r2,%r8,51,186,56
        risbg  %r3,%r8,61,178,0
        cg     %r3,904(%r10,%r2)
        lg     %r2,920(%r10,%r2)

  tcg-s390: Improve setcond

There are a variety of common cases for which we can use carry tricks to
avoid a conditional branch.  On very new hardware, use LOAD ON CONDITION
instead of a conditional branch.

  tcg-s390: Don't force -march=z990

While we still require the LONG DISPLACEMENT facility, defaults
have moved on since then.  Don't override the system compiler,
whose default may be set to z9-109 or later.
