* Make all structs readonly when applicable. It should reduce amount of needless defensive copies
* Make structs with trivial boilerplate equality code record structs
* Remove unnecessary readonly modifiers from TextureCreateInfo
* Make BitMap structs readonly too
* 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)
