RawVec: don't recompute capacity after allocating.
Currently it sets the capacity to `ptr.len() / mem::size_of::<T>()` after any buffer allocation/reallocation. This would be useful if allocators ever returned a `NonNull<[u8]>` with a size larger than requested. But this never happens, so it's not useful. Removing this slightly reduces the size of generated LLVM IR, and slightly speeds up the hot path of `RawVec` growth.
