Like TGSI_OPCODE_ARL, destination should be an integer.
This fixes invalid LLVM IR on an internal state tracker (currently Mesa
never emits this opcode).
In the future consider making ADDR register also a integer-as-float array,
like all other register kinds, or simply replace ADDR & ARR/ARL with
integer temp and instructions.

This failed to take basevertex into account:
If basevertex < 0:
(end + basevertex) might actually be in-bounds while 'end' is not.
We would have clamped in this case when we probably shouldn't.
This could break application drawing.
If basevertex > 0:
'end' might be in-bounds while (end + basevertex) might not.
We would have failed to clamp in this place. There's a comment
indicating the TNL module depends on max_index being in-bounds;
if so, it would likely break horribly.
Rather than trying to clamp correctly in the face of basevertex, simply
delete the clamping code and indicate that we don't have a valid range.
This causes _tnl_vbo_draw_prims to use vbo_get_minmax_indices() to
compute the actual bounds, which is much safer.

The application supplied [start, end] range is merely a conservative
hint of the ranges of index values inside the index buffer. There is no
requirement that all vertices in the range [start, end] be referenced.
Passing an 'end' value larger than the maximum legal index is perfectly
acceptible; applications can legally pass 0xffffffff when they don't
have a tighter bound readily available.
Thus, the warning doesn't indicate a correctness issue; it could only
indicate a performance issue. However, it does not even do that.
glDrawRangeElements is designed to optimize non-VBO vertex data uploads
by providing an upper bound on the size of buffers a driver would need
to allocate. With VBOs, the data is already in an uploaded buffer, so
the range doesn't help.
The clincher is: we only know _MaxElement for VBOs. For user-space
arrays, we just set it to 2,000,000,000 (see mesa/main/varray.h:63.)
So we can only check this in the case where it is not useful.
Many applications, including the Unigine demos, currently trigger this
warning, which suggests the applications are buggy when they're actually
fine. Eliminating the warning should confuse users less while not
actually losing any benefit to application developers.

There's a serious trap for drivers: RenderTexture() does not indicate
that the texture is currently bound to the draw buffer, despite
FinishRenderTexture() signaling that the texture is just now being
unbound from the draw buffer.
We were acting as if RenderTexture() *was* the start of rendering and
that we could make texturing incoherent with the current contents of
the renderbuffer. This caused intel oglconform sRGB
Mipmap.1D_textures to fail, because we got a call to TexImage() and
thus RenderTexture() on a texture bound to a framebuffer that wasn't
the draw buffer, so we skipped validating the new image into the
texture object used for rendering.
We can't (easily) make RenderTexture() indicate the start of drawing,
because both our driver and gallium are using it as the moment to set
up the renderbuffer wrapper used for things like MapRenderbuffer().
Instead, postpone the setup of the workaround render target miptree
until update_renderbuffer time, so that we no longer need to skip
validation of miptrees used as render targets. As a bonus, this
should make GL_NV_texture_barrier possible.
(This also fixes a regression in the gen4 small-mipmap rendering since
3b38b33c16, which switched
set_draw_offset from image->mt to irb->mt but didn't move the irb->mt
replacement up before set_draw_offset).
