I have some fixes/changes to this which I rebased on top of your latest
tree, these are available here:

http://cgit.freedesktop.org/~tpalli/mesa/log/?h=fp64_fixes

Notably the last one (i965 changes) is very experimental and should be
maybe ignored for now, others should be useful and fixes the fp64 tests
I've been sending to Piglit.

I introduced 'i2d and u2d', I'm not sure if this is wanted but it makes
implicit conversions in ast_to_hir.cpp cleaner, other option would be to
refactor implicit conversions code a bit. Let me know of your thoughts,
I can go for refactor if these are not wanted.

Thanks;

I suspect there are chunks in some patches that might need to be in other, and the uniform patches are probably not very well explained, mostly because I can't remember why exactly I did what I did in a few places.
