Check kernels before fusing
b/21958851
Kernel fusion for a Script Group expects kernels to be chained up
via outputs (return values) and first arguments.
Check this condition during fusion. Otherwise, BCC may crash on
broken invariants.

Create one single module for a script group
This changed the way we compile a script group. Instead of compiling
each batch into a seperate module, we now compile the whole script
group into one single module, with each batch as a function (of fused
kernels) in that module. This allows invoke to (fused) kernel
communication via globals variables.
Added commoand line options "-merge" and "-invoke". The former
accepts fused kernel names, input kernels, while the latter accepts
new invoke name, and the original invoke function.
Additional changes:
- Bail out on encountering any unexpected bits in the foreach
signature of any kernel to fuse
- Made kernel fusion handle kernels without inputs.
If a kernel only takes global allocations but no inputs, bcc
needs to use a different signature for the fused kernel.
- Included in rs info the exported variables for the fused kernel.
- Keep all metadata in merged module from the input modules. This
would help correctly handling FP precision. (b/19098612)
- Handles Z (b/19610223)

Compiler kernel fusion for RenderScript.
This was started by Tobias Grosser during his internship at Google in 2013.
This CL includes his original changes and generalization to make it work with
the new proposed ScriptGroup API and made the ImageProcessing processing work
with this.
An enabling CL is needed in the RenderScript runtime, which I will post
seperately.
