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
  • Property mode set to 100644
