i965: Use negative relocation deltas to minimse vertex uploads
With relaxed relocation checking in the kernel, we can specify a negative delta (i.e. pointing outside of the target bo) in order to fake a range in a large buffer. We only then need to upload the elements used and adjust the buffer offset such that they correspond with the indices used in the DrawArrays. (Depends on libdrm 0209428b3918c4336018da9293cdcbf7f8fedfb6) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
