(movdf+1): Use new 'T' and 'U' constraints to
determine when an ldd or std will have a length of 1, and
therefore is eligible for use in some delay slots.
(uncond_branch): New attribute used for unconditional branches.
All unconditional branch patterns changed to use this attribute.
(define_delays and delay slot attributes): Do not allow
uncond_branch instructions in delay slots. Do not allow fpload or
fpstore operations in a conditional branch delay slot. Allow
fpload and fpstore in call, unconditional branch, and annuled
conditional branch delay slots.
