[CallSiteSplitting] Remove isOrHeader restriction. By following the single predecessors of the predecessors of the call site, we do not need to restrict the control flow. Reviewed By: junbuml, davide Differential Revision: https://reviews.llvm.org/D40729 llvm-svn: 321413

Recommit r325001: [CallSiteSplitting] Support splitting of blocks with instrs before call. For basic blocks with instructions between the beginning of the block and a call we have to duplicate the instructions before the call in all split blocks and add PHI nodes for uses of the duplicated instructions after the call. Currently, the threshold for the number of instructions before a call is quite low, to keep the impact on binary size low.
