Subject: * Use the new reduce_apply_bool template
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=3596366bed2ec5e492d994f88ea76829a0e3d657;p=oota-llvm.git

* Use the new reduce_apply_bool template
* Expose Constant Pool Merging from ConstantProp.cpp
* Include definitions for SCCP pass
* InstListType is not neccesary anymore
