On r6xx/r7xx shader resource management need to make sure that the
shader does not goes over the gpr register limit. Each specific
asic has a maxmimum register that can be split btw shader stage.
For each stage the shader must not use more register than the
limit programmed.
v2: Print an error message when discarding draw. Don't add another
boolean to context structure, but rather propagate the discard
boolean through the call chain.
