Uday Bondhugula 01d97a3549 [MLIR] Add support to use aligned_alloc to lower AllocOp from std to llvm ... Support to recognize and deal with aligned_alloc was recently added to LLVM's TLI/MemoryBuiltins and its various optimization passes. This revision adds support for generation of aligned_alloc's when lowering AllocOp from std to LLVM. Setting 'use-aligned_alloc=1' will lead to aligned_alloc being used for all heap allocations. An alignment and size that works with the constraints of aligned_alloc is chosen. Using aligned_alloc is preferable to "using malloc and adjusting the allocated pointer to align for indexing" because the pointer access arithmetic done for the latter only makes it harder for LLVM passes to deal with for analysis, optimization, attribute deduction, and rewrites.
