[Mesa-dev] [PATCH] mesa: Add _mesa_error_no_memory for logging out-of-memory messages

[Ian Romanick]

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

This can be called from locations that don't have a context pointer
handy.  This patch also adds enough infrastructure so that the unit
tests for the GLSL compiler and the stand-alone compiler will build and
function.
