* Use a new approach for shader BRX targets * Make shader cache actually work * Improve the shader pattern matching a bit * Extend LDC search to predecessor blocks, catches more cases * Nit * Only save the amount of constant buffer data actually used. Avoids crashes on partially mapped buffers * Ignore Rd on predicate instructions, as they do not have a Rd register (catches more cases)
