f6ead50827 mesa: added OPCODE_NRM3/NRM4 instructions for vector normalization. 
We may emit these instructions from GLSL instead of DP3/RCP/MUL.

Also, implement SSG (set sign) instruction in the interpreter.

035c0cf71a mesa: rename OPCODE_INT -> OPCODE_TRUNC 
Trunc is a more accurate description; there's no type conversion involved.

517401af07 mesa: update the shader programs->TexturesUsed array at link time 
If an application never calls glUniform() to set sampler variable values
they'll remain 0 (the default value/unit).
Now call _mesa_update_shader_textures_used() at link time in case glUniform()
is never called.  program->TextureUsed[] will then be correct for state
validation.

df94fd1764 i965: Always check vertex program. 
Now i965 also uses the vertex program created by Mesa Core, but this vertex program
is not only depend on mesa state _NEW_PROGRAM, so always check the current vertex
program is updated or not. This fixes broken demo cubemap.

72c914805b Fix for 58dc8b7: dest regions must not use HorzStride 0 in ExecSize 1 
Quoting section 11.3.10, paragraph 10.2 of the 965PRM:

10.2. 	If ExecSize is 1, dst.HorzStride must not be 0. Note that this is
	relaxed from rule 10.1.2. Also note that this rule for destination
	horizontal stride is different from that for source as stated in
	rule #7.

GM45 gets very angry when rule 10.2 is violated.

Patch 58dc8b7 (i965: support destination horiz strides in align1 access mode)
added support for additional horizontal strides in the ExecSize 1 case, but
failed to notice that mesa occasionally re-purposes a register as a
temporary destination, even though it was constructed as a repeating source
with HorzStride = 0.

While, ideally, we should probably fix the code using these register
specifications, this patch simply rewrites them to use HorzStride 1 as the
pre-58dc8b7 code did.
