Rollup merge of #23322 - dotdash:jemalloc_attrs, r=brson
When this attribute is applied to a function, its return value gets the noalias attribute, which is how you tell LLVM that the function returns a \"new\" pointer that doesn't alias anything accessible to the caller, i.e. it acts like a memory allocator. Plain malloc doesn't need this attribute because LLVM already knows about malloc and adds the attribute itself.
