Zihao Yu 66dcd98e39 native,platform: clear the FPU context in uc_example 
* This will fix the SIGSEGV sent by 4.19 kernel. It seems the cause is
  that a page fault is generated when restoring the FPU context with an
  fxrstor64 instruction. To work around, we just clear the FPU context
  in uc_example, so the kernel will not try to restore the FPU context.

README 

AbstractMachine is a minimal, modularized, and machine-independent 
abstraction layer of the computer hardware:

* physical memory and direct execution (The "Turing Machine");
* basic model for input and output devices (I/O Extension);
* interrupt/exception and processor context management (Context Extension);
* virtual memory and protection (Virtual Memory Extension);
* multiprocessing (Multiprocessing Extension).
