[PATCH][Cilkplus] Patch to remove CILKPLUS IMPLEMENTED macro

[Iyer, Balaji V]

Hello Everyone,
    This patch is for the Cilkplus branch, affecting both C and C++ compilers. 
This patch will remove the CILKPLUS_IMPLEMENTED macro and all the #ifdef and 
#ifndef that uses it.

   This is patch #3.

Thanks,

Balaji V. Iyer.
