With this patch, guest statistic gathering interface is added to
svga winsys interface that can be used to gather svga driver
statistic. The winsys module can then share the statistic info with
the VMX host via the mksstats interface.
The statistic enums used in the svga driver are defined in
svga_stats_count and svga_stats_time in svga_winsys.h

svga_shader_expand() will fall back to using non-malloced memory for
emit.buf if malloc fails. We should check if the memory is malloced
before freeing it in the error path of svga_tgsi_vgpu9_translate.

Use NULL tests of the form `if (ptr)' or `if (!ptr)'.
They do not depend on the definition of the symbol NULL.
Further, they provide the opportunity for the accidental
assignment, are clear and succinct.

Examine the fragment shader to try to detect TGSI shaders which use
"MOV OUT[0], CONST[i]" to write a constant value for the fragment color.
In this case, all fragments will have the same color (unless blending is
enabled).
This is a common case for OpenGL code such as: glColor(), glBegin(),
glVertex(), ..., glEnd() when lighting/fog/etc are disabled. In this
case, the Mesa/gallium state tracker actually generates a simple
"MOV OUT[0], CONST[i]" fragment shader.
This will be used by the next commit to avoid provoking vertex conversion
(creating/rewriting an index buffer) when drawing flat-shaded primitives.

This code actually hasn't been needed for some time now. We can just
treat a zero-stride vertex array like any other non-zero-stride array.

And assert on the register index in dst_register(). The dest can
only be an output or temp reg and there's more of the later.

If the VS has outputs that aren't consumed by the FS we were mapping
them all to one unused VS output index, but that's illegal. Instead,
map unused VS outputs to unique indexes.

The state tracker may generate shaders that use generic vs outputs /
fs inputs like:
DCL IN[0], GENERIC[0]
DCL IN[1], GENERIC[10]
DCL IN[2], GENERIC[11]
This patch remaps 0, 10, 11 to small integers like 1, 2, 3 so that we
stay inside the SVGA3D limit (8).
The remapping is done to both the vertex shader outputs and the
fragment shader inputs. The same mapping must be used for a vs/fs
pair.
Note that 'union svga_compile_key' is now 'struct svga_compile_key'
because we needed to add the register remapping table. The change in
size isn't really significant though (it's not a search key).
Also, add assertions when building up SVGA3D src/dst registers to we
don't try to store too large of value for the bitfield size.

Previously we were using a hodge podge of int vs. pipe_enum and
0 vs. PIPE_OK. Some functions that always returned PIPE_OK were
made void.

Count int and float constants independently. Since there are only
few i# constants available and hundreds of c# constants, it would
be too easy to end up with an i# declaration out of its range.
