No need to schedule entry nodes where all instructions are not memory read/write instructions and their operands are either constants, or arguments, or phis, or instructions from others blocks, or their users are phis or from the other blocks. The resulting vector instructions can be placed at the beginning of the basic block without scheduling (if operands does not need to be scheduled) or at the end of the block (if users are outside of the block). It may save some compile time and scheduling resources. Differential Revision: https://reviews.llvm.org/D121121
