This should reduce memory consumption.

1) Only translate the [min_index, max_index] range.
2) Upload translated vertices via the uploader.

This fixes:
- piglit/draw-vertices
- piglit/draw-vertices-half-float

Note the support for non float vertex draw likely regressed need to
find what we want to do there.

Avoid rebuilding constant shader state at each draw call,
factor out spi update that might change at each draw call.
Best would be to update spi only when revealent states
change (likely only flat shading & sprite point).

Vertex elements change are less frequent than draw call, those to
avoid rebuilding fetch shader to often build the fetch shader along
vertex elements. This also allow to move vertex buffer setup out
of draw path and make update to it less frequent.
Shader update can still be improved to only update SPI regs (based
on some rasterizer state like flat shading or point sprite ...).

Tested with piglit + ut2004 still seems to render okay (and it
definitely does this)

no point duplicating code that doesn't touch hw, also make it easier
to spot mistakes
