  Modified files:
    sys/amd64/ia32       ia32_sigtramp.S 
  Log:
  Stop reloading %fs and %gs, since it causes the base address from
  GDT to be loaded into FS.base and GS.base, these values of course
  are not the values set by sysarch() with I386_SET_FSBASE and
  I386_SET_GSBASE, the change fixed a crash for 32bit libthr after
  signal handler returned and normal code is accessing thread pointer,
  for example: movl %gs:8, %eax.
