This revision introduces a generic implementation of Scalar Replacement Of Aggregates. In contrast to the implementation in LLVM, this focuses on the core of SROA: destructuring aggregates. By implementing interfaces on allocators and accessors, memory allocators can be destructured into smaller allocators, through the MemorySlot abstraction. This pass only works on aggregates that are accessed in a "type-safe" way, that is within the bounds and respecting the type of a given memory slot. The destructuring pattern and functions only peel off the first layer of aggregates and can safely be applied repeatedly. For convenience, the transformation is also available as a pass that will apply the pattern repeatedly. Depends on D149958 Reviewed By: gysit Differential Revision: https://reviews.llvm.org/D150186
