The VMware svga driver doesn't directly support pipe_screen::get_timestamp()
but we can do a work-around. However, we need a gallium context to do so.
This patch adds a new pipe_context::get_timestamp() function that will only
be called if the pipe_screen::get_timestamp() function is NULL.

If the user is specifying a subregion of a buffer using SKIP_ROWS and
SKIP_PIXELS, we must compute the buffer size carefully as the end of the
last row may be much shorter than stride*image_height*depth. The current
code tries to memcpy from beyond the end of the user data, for example
causing:

The src_reg constructor that received the glsl_type was using it
only to build the swizzle, but not to fill this->type as dst_reg
is doing.
This caused some type mismatch between movs and alu operations
on the NIR path, so copy propagation optimization was not applied
to remove unneeded movs if negate modifier was involved. This was
first detected on minus (negate+add) operations.

This adds a tgsi utility tgsi_add_aa_point to transform a fragment shader
to support anti-aliased wide point by computing the fragment distance from
the point center. This utility assumes the geometry shader is emitting
an extra generic output with point coord data. The semantic index of
this generic output is passed to the tgsi_add_aa_point utility.

This adds a tgsi utility tgsi_add_point_sprite to transform a geometry
shader to emulate wide points by drawing quads. This utility adds an

add a constant for inverse viewport scale after the user defined constants.

This could be used by any driver where the device doesn't directly
support two-sided lighting. This code modifies a fragment shader
to accecpt back-face colors and choose between the front/back colors
depending on the triangle's front-face sign.
These functions deal with inclusive coordinates, hence a 0/0/0/0 rect
returned when there's no intersection doesn't actually represent an empty
rectangle. Hence return 0/-1/0/-1 instead.
This fixes some problems in llvmpipe with empty scissor rects (which up
to now didn't really matter because while the intersect test returned the
wrong result all pixels were scissored away later anyway).
It isn't really obvious if intersection test should take into account empty
rectangles or if the caller should do it. But it looks like most callers
actually verified one of the rects but not the other, but since correctly
returning an empty rect that other rect could actually be empty leading to
more bugs. Hence just verify both rects for emptyness in the intersection
test itself which makes the code easier in the caller (though it will be
slower if the caller knows the rectangles are non-empty).
