ad43499fc4 dependence analysis 
Patch from Preston Briggs <preston.briggs@gmail.com>.

This is an updated version of the dependence-analysis patch, including an MIV
test based on Banerjee's inequalities.

It's a fairly complete implementation of the paper

    Practical Dependence Testing
    Gina Goff, Ken Kennedy, and Chau-Wen Tseng
    PLDI 1991

It cannot yet propagate constraints between coupled RDIV subscripts (discussed
in Section 5.3.2 of the paper).

It's organized as a FunctionPass with a single entry point that supports testing
for dependence between two instructions in a function. If there's no dependence,
it returns null. If there's a dependence, it returns a pointer to a Dependence
which can be queried about details (what kind of dependence, is it loop
independent, direction and distance vector entries, etc). I haven't included
every imaginable feature, but there's a good selection that should be adequate
for supporting many loop transformations. Of course, it can be extended as
necessary.

Included in the patch file are many test cases, commented with C code showing
the loops and array references.

661afe75e8 Issue description: 
SchedulerDAGInstrs::buildSchedGraph ignores dependencies between FixedStack
objects and byval parameters. So loading byval parameters from stack may be
inserted *before* it will be stored, since these operations are treated as
independent.

Fix:
Currently ARMTargetLowering::LowerFormalArguments saves byval registers with
FixedStack MachinePointerInfo. To fix the problem we need to store byval
registers with MachinePointerInfo referenced to first the "byval" parameter.

Also commit adds two new fields to the InputArg structure: Function's argument
index and InputArg's part offset in bytes relative to the start position of
Function's argument. E.g.: If function's argument is 128 bit width and it was
splitted onto 32 bit regs, then we got 4 InputArg structs with same arg index,
but different offset values.

e97a3a4b4f Fix PR14016. 
DeadArgumentElimination pass can replace one LLVM function with another,
invalidating a pointer stored in debug info metadata entry for this function.
To fix this, we collect debug info descriptors for functions before
running a DeadArgumentElimination pass and "patch" pointers in metadata nodes
if we replace a function.

Start using the AttributesImpl object to hold the value of the attributes. All
queries go through the interfaces now.

This has one unfortunate consequence. I needed to move the AttributesImpl.h file
into include/llvm. But this is only temporary! Otherwise, the changes needed to
support this would be too large.

e66f3d3ba0 Move methods out-of-line. 
The internal representation of the Attributes class will be opaque. All of the
query methods will need to query the opaque class. Therefore, these methods need
to be out-of-line.

de2fae4c7b Third try at fixing this. ;] Go back to using std::remove_if, which has 
most of the behavior we want, but wrap the predicate in one which erases
elements from the set if they pass the predicate. Oh what I wouldn't
give for a lambda here.

Let me know if the predicate wrapping is too much magic. ;]

75eac5f0eb Switch the SetVector::remove_if implementation to use partition which 
preserves the values of the relocated entries, unlikely remove_if. This
allows walking them and erasing them.

Also flesh out the predicate we are using for this to support the
various constraints actually imposed on a UnaryPredicate -- without this
we can't compose it with std::not1.

Thanks to Sean Silva for the review here and noticing the issue with
std::remove_if.
