This patch adds initial support for loop unrolling in the form of a series of utility classes which perform the unrolling. The pass can be run with the command spirv-opt --loop-unroll. This will unroll loops within the module which have the unroll hint set. The unroller imposes a number of requirements on the loops it can unroll. These are documented in the comments for the LoopUtils::CanPerformUnroll method in loop_utils.h. Some of the restrictions will be lifted in future patches.
