estimate

[Deneau, Tom]

Gilles --

This is working well for us and it also passes tests on some early HSA hardware we have.

Let me know what kind of coordination you refer to below.
I guess there's not yet quite a clean line between the hsail-dependent part and the hsail-independent part.
Maybe you can send a proposal on what you would like for such an interface.
