draw: fix splitting of line loops (v2)

When the draw module splits long line loops, the sections are emitted
as line strips.  But the primitive type wasn't set correctly so each
section was being drawn as a loop, introducing extra line segments.

To fix this, we pass a new DRAW_LINE_LOOP_AS_STRIP flag to the run()
function.  The linear/elt_run() functions have to check for this flag
and set their primitive type accordingly.

vbo: fix GL_LINE_LOOP stray line bug

When long GL_LINE_LOOP primitives don't fit in one vertex buffer they
have to be split across buffers.  The code to do this was basically correct
but drivers had to pay special attention to the _mesa_prim::begin,end flags
in order to draw the sections of the line loop properly.  Apparently, the
only drivers to do this were those using the old 'tnl' module for software
vertex processing.

Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP
primitives so that drivers don't have to worry about the special begin/end
flags.  The only time a driver will get a GL_LINE_LOOP prim is when the
whole thing fits in one vertex buffer.

Mostly fixes bug 81174, but not completely.  There's another bug somewhere
in the src/gallium/auxiliary/draw/ code.  If the piglit lineloop test is
run with -count 4096, rendering is correct, but with -count 4097 there are
stray lines.  4096 is a magic number in the draw code (search for "4096").

Also note that this does not fix long line loops in display lists.  The
next patch fixes that.

v2: fix incorrect -1 in vbo_compute_max_verts(), per Charmaine.  Remove
incorrect assertion which was added in vbo_copy_vertices().

vbo: reduce number of vertex buffer mappings for vertex attributes

Whenever we got a glColor, glNormal, glTexCoord, etc. call outside a
glBegin/End pair, we'd immediately map a vertex buffer to begin
accumulating vertex data.  In some cases, such as with display lists,
this led to excessive vertex buffer mapping.  For example, if we have
a display list such as:

glNewList(42, GL_COMPILE);
glBegin(prim);
glVertex2f();
...
glVertex2f();
glEnd();
glEndList();

Then did:

glColor3f();
glCallList(42);

We'd map a vertex buffer as soon as we saw glColor3f but we'd never
actually write anything to it.  Note that the vertex position data
was put into a vertex buffer during display list compilation.

With this change, we delay mapping the vertex buffer until we actually
have a vertex to write to it (triggered by a glVertex() call).  In the
above case, we no longer map a vertex buffer when setting the color and
calling the list.

For drivers such as VMware's, reducing buffer mappings gives improved
performance.

i965/fs: Consider type mismatches in saturate propagation.

NIR considers bcsel to produce and consume unsigned types, leading to
SEL instructions operating on unsigned types when the data is really
floating-point. Previous to this patch, saturate propagation would
happily transform

   (+f0) sel      g20:UD, g30:UD, g40:UD
         mov.sat  g50:F,  g20:F

into

   (+f0) sel.sat  g20:UD, g30:UD, g40:UD
         mov      g50:F,  g20:F

But since the meaning of .sat is dependent on the type of the
destination register, this is not valid.

Instead, allow saturate propagation to change the types of dest/source
on instructions that are simply copying data in order to propagate the
saturate modifier.
