  Modified files:
    sys/sparc64/include  frame.h reg.h ucontext.h 
    sys/sparc64/sparc64  exception.S genassym.c intr_machdep.c 
                         machdep.c swtch.S trap.c 
  Log:
  - Expand struct trapframe to 256 bytes, make all fields fixed width and the
    same size.  Add some fields that previously overlapped with something else
    or were missing.
  - Make struct regs and struct mcontext (minus floating point) the same as
    struct trapframe so converting between them is easy (null).
  - Add space for saving floating point state to struct mcontext.  This requires
    that it be 64 byte aligned.
  - Add assertions that none of these structures change size, as they are part
    of the ABI.
  - Remove some dead code in sendsig().
  - Save and restore %gsr in struct trapframe.  Remember to restore %fsr.
  - Add some comments to exception.S.
