v850 port: Initial addition with BSP for simulator in GDB

Port
  + v850 does not have appear to have any optimized bit scan instructions
  + v850 does have single instructions for wap u16 and u32
  + Code path optimization preferences set
  + Add BSP variants for each GCC CPU model flag and a README
    - v850e1 variant does not work (fails during BSP initialization)
BSP for GDB v850 Simulator
  + linkcmds matches defaults in GDB simulator with RTEMS mods
  + crt1.c added from v850 newlib port for __main()
  + BSP exits cleanly
  + printk and console I/O work
  + uses clock tick from IDLE task
  + Tests not requiring real clock ISR work
Documentation
  + CPU Supplment chapter for v850 added

+This directory contains a family of BSPs for the v850 simulator
+found in the GNU Debugger. A variant is provided for each CPU
+model option flag found in the GCC SVN head as of 30 May 2012.
+
+This simulator is an instruction simulator and does not include
+devices for a clock tick or benchmark timer driver. Traps are used
+to provide console I/O.
