The GL spec says out of bounds fetches produce undefined results.
Use clamping to avoid failed assertions or crashes.

With this feature enabled, the LLVM backend will dump the MachineIntrs
prior to emitting code. The mesa env variable R600_DUMP_SHADERS will enable
this feature in the backend.

We can't delete MASK_WRITE instructions from the program, because this
will cause instructions being masked by MASK_WRITE to be marked dead and
then deleted in the dce pass.
Enabled MESA_FORMAT_RGBX8888_REV for RGBX. Android software
requires RGBX8888 format to be supported for software rendering.
That requires EGL to be capable of generating images from this
format.

Only images created with intel_create_image() had the field properly
set. Set it also on intel_dup_image(), intel_create_image_from_name()
and intel_create_image_from_renderbuffer().
GL_ARB_texture_storage says:
The commands eglBindTexImage, wglBindTexImageARB, glXBindTexImageEXT or
EGLImageTargetTexture2DOES are not permitted on an immutable-format
texture.
They will generate the following errors:
- EGLImageTargetTexture2DOES: INVALID_OPERATION
- eglBindTexImage: EGL_BAD_MATCH
- wglBindTexImage: ERROR_INVALID_OPERATION
- glXBindTexImageEXT: BadMatch
Fixing the EGL and GLX cases requires extending the DRI interface,
since setTexBuffer2 doesn't currently return any error information.

Adapted drivers: i915, llvmpipe, r300, r600, radeonsi, softpipe.
User index buffers have been disabled in nv30, nv50, nvc0 and svga to keep
things working.
This reduces CPU overhead in st_draw_vbo and removes a lot of unnecessary code
in that function which was required only to comply with the gallium interface,
but wasn't any useful really.

No changes required in: r600, radeonsi.
User vertex buffers have been disabled in nv30, nv50, nvc0 and svga to keep
things working.
This is required for any serious constant buffer support.
Constant buffer offsets on ATI and NVIDIA DX10 and DX11 GPUs must be
a multiple of 256.
In OpenGL, this can be queried via GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT.
