compiler: fix slice/array evaluation order bug

    There was a phase ordering issue in the handling of "keyed" array
    literal expressions: the lowering phase was canonicalizing the
    indices/vals before the phase that fixed evaluation order, meaning that
    the evaluation order was incorrect. The fix is to capture the orginal
    ordering and use that ordering when doing traversals (there is already
    something similar being done for struct literal expressions).

    Fixes golang/go#17640

combine: Improve change_zero_ext (fixes PR71847)

This improves a few things in change_zero_ext.  Firstly, it should use
the passed in pattern in recog_for_combine, not the pattern of the insn
(they are not the same if the whole pattern was replaced).  Secondly,
it handled zero_ext of a subreg, but with hard registers we do not get
a subreg, instead the mode of the reg is changed.  So this handles that.
Thirdly, after changing a zero_ext to an AND, the resulting RTL may become
non-canonical, like (ior (ashift ..) (and ..)); the AND should be first,
it is commutative.  And lastly, zero_extract as a set_dest wasn't handled
at all, but now it is.

This fixes the testcase in PR71847, and improves code generation in some
other edge cases too.

sched: Do not mix prologue and epilogue insns

This patch makes scheduling not reorder prologue insns relative to
epilogue insns and vice versa.  This fixes PR78029.

The problem in that PR:
We have two insns, in this order:

(insn/f 300 299 267 8 (set (reg:DI 65 lr)
        (reg:DI 0 0)) 579 {*movdi_internal64}
     (expr_list:REG_DEAD (reg:DI 0 0)
        (expr_list:REG_CFA_RESTORE (reg:DI 65 lr)
            (nil))))
...
(insn/f 310 268 134 8 (set (mem/c:DI (plus:DI (reg/f:DI 1 1)
                (const_int 144 [0x90])) [6  S8 A8])
        (reg:DI 0 0)) 579 {*movdi_internal64}
     (expr_list:REG_DEAD (reg:DI 0 0)
        (expr_list:REG_CFA_OFFSET (set (mem/c:DI (plus:DI (reg/f:DI 1 1)
                        (const_int 144 [0x90])) [6  S8 A8])
                (reg:DI 65 lr))
            (nil))))

and sched swaps them (when compiling for power6, it tries to put memory
stores together, so insn 310 is moved up past 300 to go together with
some other store).  But the REG_CFA_RESTORE and REG_CFA_OFFSET cannot be
swapped (they both say where the orig value of LR now lives).

Adapt atomic compare and swap to ARMv8-M Baseline

2016-10-26  Thomas Preud'homme  <thomas.preudhomme@arm.com>

    gcc/
    * config/arm/sync.md (atomic_compare_and_swap<mode>_1): Add new ARMv8-M
    Baseline only alternatives to (i) hold store atomic success value in a
    return register rather than a scratch register, (ii) use a low register
    for it and to (iii) ensure the cbranchsi insn generated by the split
    respect the constraints of Thumb-1 cbranchsi4_insn and
    cbranchsi4_scratch.
    * config/arm/thumb1.md (cbranchsi4_insn): Add comment to indicate
    constraints must match those in atomic_compare_and_swap.

Refactor atomic compare_and_swap to make it fit for ARMv8-M Baseline

2016-10-26  Thomas Preud'homme  <thomas.preudhomme@arm.com>

    gcc/
    * config/arm/arm.c (arm_expand_compare_and_swap): Add new bdst local
    variable.  Add the new parameter to the insn generator.  Set that
    parameter to be CC flag for 32-bit targets, bval otherwise.  Set the
    return value from the negation of that parameter for Thumb-1, keeping
    the logic unchanged otherwise except for using bdst as the destination
    register of the compare_and_swap insn.
    (arm_split_compare_and_swap): Add explanation about how is the value
    returned to the function comment.  Rename scratch variable to
    neg_bval.  Adapt initialization of variables holding operands to the
    new operand numbers.  Use return register to hold result of store
    exclusive for Thumb-1, scratch register otherwise.  Construct the
    appropriate cbranch for Thumb-1 targets, keeping the logic unchanged
    for 32-bit targets.  Guard Z flag setting to restrict to 32bit targets.
    Use gen_cbranchsi4 rather than hand-written conditional branch to loop
    for strongly ordered compare_and_swap.
    * config/arm/predicates.md (cc_register_operand): New predicate.
    * config/arm/sync.md (atomic_compare_and_swap<mode>_1): Use a
    match_operand with the new predicate to accept either the CC flag or a
    destination register for the boolean return value, restricting it to
    CC flag only via constraint.  Adapt operand numbers accordingly.
