The src/dst arrays would overlap but dst was less than src so a simple
version of memcpy() would do the right thing. But this isn't guaranteed
when memcpy() is optimized.
Fixes demos/copypix when the dest region was clipped by the left side of
the window.

Do it after we check whether inst_end != -1.
Also move the code structure at the beginning of r300_fragment_shader_code
to detect underflows easily with valgrind.
Improves performance from cca 1 fps to 23 fps in Cogs.
This new codepath is not always used, instead, there is a heuristic which
determines whether to use it. Using translate for uploads is generally
slower than what we have had already, it's a win only in a few cases.
This is for GL_ARB_vertex_type_2_10_10_10_rev.
I just took the code from u_format_table.c. It's based on pack_rgba_float.
I had no other choice. The u_format hooks are not exactly compatible
with translate. The cleanup of it is left for future work.

The conversion is limited to only a few cases, because converting to any other
type shouldn't happen in any driver.

Fetching int as float and vice versa is not allowed.
Fetching unsigned int as signed int and vice versa is not allowed either.
Doing conversions like that isn't allowed for samplers in OpenGL.
The three hooks could be consolidated into one fetch hook, which would fetch
uint as uint32, sint as sint32, and everything else as float. The receiving
parameter would be void*. This would be useful for implementing vertex fetches
for shader model 4.0, which has untyped registers.

This paves the way for moving user buffer uploads out of drivers and should
allow to clean up the mess in u_upload_mgr in the meantime.
For now only allowed for buffers on r300 and r600.

We don't wanna convert per-instance or constant (zero-stride) attribs into
ordinary vertex attribs.
More importantly, the translation of instance attribs now finally works.
To match what transfer_map returns. Really, subtracting the offset leads
to bugs if someone expects it to work exactly like transfer_map.

This reverts commit 5a478976ae.
It broke the build. DRI drivers were no longer being installed by
`make install` (and probably not being built at all). It appears to be
due to a few small, subtle mistakes, and the fix isn't clear enough to
simply commit without going through review. In the meantime, revert it.
All other xorg modules require at least 2.60 (released in 2006), so we
may as well increase it to match. It's also doubtful anyone tests the
build with 2.59 (from 2003), so it may not even work anyway.
Adds two missing '|| srcFormat == GL_RG_INTEGER' in assertions and a
bunch of missing pixel converions cases.

textureSize() returns an int, ivec2, or ivec3, but never an ivec4.
Creating the destination register as an ivec4 triggered later failures,
even though the register did hold the proper values.
For example, piglit test vs-textureSize-compare calls textureSize on a
2D texture and compares the result to an expected value. Unfortunately,
our generated code also tried to compare the third and fourth components
which were undefined, and failed.
Fixes piglit test vs-textureSize-compare as well as 19 subcases of
oglconform's glsl-bif-tex-size test.

Other parts of the compiler assume that expressions will have
well-formed types or the error type. Just using the type of the thing
being operated on can cause expressions like ~3.14 or ~false to not
have a well-formed type. This could then result in an assertion
failure in the context epxression handler.
If there is an error processing the expression, set the type of the IR
expression to error.
