- Changed all benchmarks accordingly
- GenVISC implementation updated accordingly

Added argument to __visc__edge to allow user to specify 1-to-1 or all-to-all edge. all-to-all = true, one-to-one = false

    - IntrinsicsVISC.td, visc.h, GenVISC.cpp
(2) Simplified GenVISC to easily add support for new intrinsics which have a 1
to 1 mapping instruction during code gen
(3) Added runtime api call to set ocl shared memory argument

Revert back to using __visc__init and cleanup without arguments. That is, they are no more DFG specific, rather just hints for compiler to insert compilation code
