x86: Two minor optimizations: Ignore transpose for vmidt/vmone/vmzero, save a MOV in many cases of "jr ra"
Make ExtractIR no longer a member function of the Jit classes. Unify JitOptions across the backends (required for that)
jit viewer: Make it possible to quickly find blocks with FP instructions
Fix some fp instruction in/out flags
Re-enable joint VROT
Jit IR: Add "clobbered" flags. Apply FlushRemap to some FPR operations as well.

Use to avoid writeback when FlushRemap-ing when possible - however, disabled the optimization.
Missing flags in MIPSTables? Or doesn't work right until we unfold delay slots..
