Annotate allocations with Renderscript TBAA metadata
We extend the RSForEachExpand pass to emit Renderscript TBAA metadata.
This allows us to prove the absence of aliasing between accesses to to
allocations and other data accesses. This is especially useful as it enables
the compiler often to hoist loop invariant globals out of the compute loop.

ForEach: Not all kernels are expanded
Bug: 9674197
There may be some graphics root functions that are not expanded
and can consequently not be marked as internal linkage.

ForEach: Set internal linkage for kernel functions
The expanded function is the external visible interface. Setting internal
linkage will influence the cost function of the inliner. Specifically, the
inliner knowns that no external users will use the unexpanded kernel function,
which means it will inline it and remove the original function.
This gives a 22% speedup on the colorcube 3D, 19% on convolve3x3
as well as minor speedups on fisheye.

ForEachExpand: Use consistently unsigned integers in loop
Previously we used an signed compare in the loop exit condition, but claimed
the absence of unsigned integer wrapping. We now use an unsigned comparison
reflecting that our integers are interpreted as unsigned values.

ForEachExpand: Construct loop in a separate function
When expanding the loading/unloading of parameter values as well as the
creation of the implicit loop where mangled together. We now separate
them. This reduces code duplication and makes the difference between
the two ways of expanding a kernel more clear.
We also add some documentation and a FIXME that highlights the
surprising use of NUW during code generation.
The only functional change included here is that we switch to using PHI-nodes
instead of loading/storing the loop iterator to memory.

ForEachExpand: Create a complete function
In createEmptyExpandedFunction() we now create a complete function containing a
single basic block that directly returns. The advantage of creating a complete
function is that it allows us to maintain valid LLVM-IR throughout the whole
expansion process. This makes testing easier as commenting out later code does
not yield invalid LLVM-IR.
No functional change intended.

Fix pass-by-value when the return type uses pass-by-reference.
Since we are using a baseline ARM ABI for Renderscript's portable bitcode,
we need to handle the case where a large return value gets passed as a
pointer (it becomes the first argument). This also fixes a small issue
where the first argument could be the return value (i.e. passed by
reference). I also have verified that coerced struct pass-by-value is
now working with this change.

Implement expandKernel() for pass-by-value.
This change implements the libbcc portion of pass-by-value in RS kernels.
The expandKernel() function creates the appropriate loop construct around
the kernel call (thus foo() -> foo.expand()).
