We should add some hashtable benchmarks into our set of benchmarks. It's a rather central data structure to the compiler but also most programs. Ideally the benchmark would be targeted against a generic interface so that it can be used to compare the wealth of hashtables that we will eventually offer. =)

I'm closing this since there's a generic core-map benchmark now. It would be useful to benchmark the hash separately though and compare to optimized SipHash 2-4 implementations.

Fix codegen_atomic_binop for atomic_ptr (rust-lang#3047)
73b4c47 
Fetch functions of `atomic_ptr` calls atomic intrinsic functions with
pointer-type arguments (`invalid_mut`), which will cause typecheck
failures. The change in this commit add support of pointer-type
arguments into `codegen_atomic_binop` to fix the issue. The new
`codegen_atomic_binop` will cast pointer arguments to `size_t`, apply op
on them, and then cast the op result back to the pointer type.

The new test include all fetch functions of `atomic_ptr` except for
`fetch_ptr_add` and `fetch_ptr_sub`, which do not call intrinsic
functions.

Resolves rust-lang#3042.
