2019-10-28tcg: let plugins instrument virtual memory accessesEmilio G. Cota
To capture all memory accesses we need hook into all the various helper functions that are involved in memory operations as well as the injected inline helper calls. A later commit will allow us to resolve the actual guest HW addresses by replaying the lookup. Signed-off-by: Emilio G.

2019-10-28plugin-gen: add module for TCG-related codeEmilio G. Cota
We first inject empty instrumentation from translator_loop. After translation, we go through the plugins to see what they want to register for, filling in the empty instrumentation. If if turns out that some instrumentation remains unused, we remove it. This approach supports the following features: - Inlining TCG code for simple operations. Note that we do not export TCG ops to plugins. Instead, we give them a C API to insert inlined ops. So far we only support adding an immediate to a u64, e.g. to count events. - "Direct" callbacks. These are callbacks that do not go via a helper. Instead, the helper is defined at run-time, so that the plugin code is directly called from TCG. This makes direct callbacks as efficient as possible; they are therefore used for very frequent events, e.g. memory callbacks. - Passing the host address to memory callbacks. Most of this is implemented in a later patch though. - Instrumentation of memory accesses performed from helpers. See the corresponding comment, as well as a later patch. Signed-off-by: Emilio G.

Change the handling of port F0h writes and FPU exceptions to implement IGNNE. The implementation mixes a bit what the chipset and processor do in real hardware, but the effect is the same as what happens with actual FERR# and IGNNE# pins: writing to port F0h asserts IGNNE# in addition to lowering FP_IRQ; while clearing the SE bit in the FPU status word deasserts IGNNE#.
