[patch] implement Cilk Plus simd loops on trunk


Hi Jason.  Hi Richard.

Attached is a patch implementing the <#pragma simd> construct from Cilk Plus on trunk. The approach is to generate a CILK_SIMD tree code which eventually gets gimplified into a gimple for with appropriate annotation reminding us that it was a Cilk loop construct. OpenMP does the rest.

This patch is dependent on the OMP4 bits I have just submitted.

Tested on x86-64 Linux.

OK for trunk (pending separate OMP_SIMD bits approval)?
