Because of this Tracy starts an additional thread and includes code for performing on-the-fly DXT1 texture compression. Since we never need this it'd be nice to be able to toggle all of that off to reduce the code size impact and extra runtime threads.

Note that the FIRRTL ops encode the sign of the operation into the types of the operands. We should use MLIR/LLVM style comparisons that embed the signedness into the operation name themselves, e.g. like [std.cmpi](https://mlir.llvm.org/doc

Our BConv op has a few parameter combinations where it can throw during Init or Prepare. In the converter we try to make sure that none of those cases will ev
