Matt Borgerson b2ea6450d8 target/i386: Check CR0.TS before enter_mmx ... When CR0.TS=1, execution of x87 FPU, MMX, and some SSE instructions will cause a Device Not Available (DNA) exception (#NM). System software uses this exception event to lazily context switch FPU state. Before this patch, enter_mmx helpers may be generated just before #NM generation, prematurely resetting FPU state before the guest has a chance to save it.
