[3/3] wined3d: Constant load optimisations

This patch is built on top of Part 1/2, and is replacing constant heap logic.
Oprofile shows that quite a lot of wined3d CPU is used in constant
heap maintenance and walks.

As DX initially sends constant ranges to be updated, splitting ranges
into individual
constant updates (through heap versionning) should be avoided if
possible. Especially
if we intend to send GL ranges at the end.

This patch maintains (and somewhat merges) ranges sent to DX, so that
(to be renamed ?) can directly issue range updates.
