This patch series adds the branch and integer instructions that were 
introduced in Power ISA 2.07.  Specifically,

  - There is a new conditional Branch to Address Register (bctar) instruction.
  - The load/store quadword instructions are now supported in user mode (Book 
I).
  - Quadword atomic instructions have been added (lqarx, stqcx.).

ISA 2.07 additions for other categories (VSX, Altivec, Decimal Floating Point,
transactional memory) are not included in this patch series; they will be 
contributed via other patches.

V2: Addressing review comments from Alex Graf:
    (1) Refactored user-mode and Little Endian checks in the load and store
        quadword instructions.
    (2) Added reserve_val2 element to CPU state in support of quadword atomic
        instructions.

V3: Addressiew review comments from Alex Graf:
    (1) Moved declaration of local variables to the beginning of the block (a la
        C89 standard).
    (2) Fixed bugs in handling of secondary reservation doubleword used in lqarx
        and stqcx. instructions.
