xtensa: Reflect the 32-bit Integer Divide Option

On Espressif's ESP8266 (based on Tensilica LX106, no hardware divider),
this patch reduces the size of each:

  __moddi3() @ libgcc.a :  969 -> 301 (saves 668)
  __divmoddi4()         : 1111 -> 426 (saves 685)
  __udivmoddi4()        : 1043 -> 319 (saves 724)

in bytes, respectively.

gcc/ChangeLog:

* config/xtensa/xtensa.h (TARGET_HAS_NO_HW_DIVIDE): New macro
definition.
