[PATCH] D9766: Add support for complex aggregate store in InstCombine

[Amaury SECHET via llvm-commits]

Pretty much all frontend need to manipulate aggregate. clang is no exception. Right now all frontend use a set of trick to make that work. clang does it via doing memcpy of the struct into an alloca and letting SROA do the work.

I can do the same on my own or we can facilite frontend writter life by handling aggregates properly. The later is preferable.
