This commit drops libptc in favor of its new form libtcg. It brings several improvements, among which: * The QEMU version we work on has been upgraded. * CPUStateAccessAnalysis has been reimplemented in a way that makes it easier to debug and solves some limitations (e.g., tracking leaking pointers). * Identification of pieces of the CPU state that are read by each helper and fixing access to the CPU state is now performed at build-time. * We no longer mmap the code we need to translate, dropping all the issues related to code that needed to be mapped where something is already present. * We now have two distinct flavors of helper modules: the full one and the "slim" one. The latter contains the definition only of functions we intend to inline. It is used in most of the pipeline, a good thing since we spend less time optimizing code we don't really care about. The full module is only used on the re-compilation branch of the pipeline. * We no longer split the `cpu_loop` function. * We change MetaAddress to rely on architectures from `model::` as opposed to the LLVM ones. * We no longer attach debug info to LLVM IR containing the original assembly. * We now verify that the lifted code only contains code we expect.
