mesa: Make glBindBufferBase/glBindBufferRange() work on just-genned names.

In between glGenBuffers() and glBindBuffer(), the buffer object points to this
dummy buffer with a name of 0, and a glBindBufferBase() would point to that.
It seems pretty clear, given that glBindBufferBase() only cares about the
current size of the buffer at render time, that it should bind up the buffer
that you passed in instead of pointing it at this useless dummy buffer.

However, what should glBindBufferRange() do?  As of this patch, it will
promote the genned buffer to a proper buffer like it had been
glBindBuffer()ed, and then detect that the size is greater than the buffer's
current size of 0 and throw INVALID_VALUE.  It seems like the most reasonable
answer here.

Note that this also changes the behavior of these two on non-glGenBuffers() bo
names.  We haven't yet set up the error throwing for glBindBuffers() on gl
3.1+, and my assumption is that these two functions should inherit their

i965/fs: Don't clobber sampler message MRFs with subexpressions.

Consider a texture call such as:

   textureLod(s, coordinate, log2(...))

First, we begin setting up the sampler message by loading the texture
coordinates into MRFs, starting with m2.  Then, we realize we need the
LOD, and go to compute it with:

   ir->lod_info.lod->accept(this);

On Gen4-5, this will generate a SEND instruction to compute log2(),
loading the operand into m2, and clobbering our texcoord.

Similar issues exist on Gen6+.  For example, nested texture calls:

  textureLod(s1, c1, texture(s2, c2).x)

Any texturing call where evaluating the subexpression trees for LOD or
shadow comparitor would generate SEND instructions could potentially
break.  In some cases (like register spilling), we get lucky and avoid
the issue by using non-overlapping MRF regions.  But we shouldn't count
on that.
