[Mesa-stable] [PATCH 08/13] mesa: Add STATE_BASE_VERTEX

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

This is a "uniform" that represents the basevertex value passed to
glDrawElementsBaseVertex and related functions.  For hardware that does
not implement a hardware register for SYSTEM_VALUE_BASE_VERTEX, passing
the value via a uniform is the only way to implement the functionality.
