Cameron Zwarich e0b4705b03 Add support to scalar replacement for partial vector accesses of an alloca, e.g. a union of a float, <2 x float>, and <4 x float>. This mostly comes up with the use of vector intrinsics, especially in NEON when programmers know the layout of the register file. This enables codegen to eliminate a lot of the subregister traffic it would otherwise generate. This commit only enables this for a small number of floating-point cases, but a lot more integer cases. I assume this is okay for all ports, but I did not do extensive testing of the quality of code involving i512 vectors and the like. If there is a use case where this generates worse code than before, let me know and we can scale it back. This fixes <rdar://problem/9036264>. llvm-svn: 127317		2011-03-09 05:43:05 +00:00
