This bug is fixed with Eric's patch.
clang trunk -O3 generates:
```
f1(): # @f1()
push r14
push rbx
push rax
mov rbx, rdi
xorps xmm0, xmm0
movups xmmword ptr [rdi], xmm0
mov qword ptr [rdi + 16], 0
mov edi, 8294400
call operator new(unsigned long)
mov qword ptr [rbx], rax
lea r14, [rax + 8294400]
mov qword ptr [rbx + 16], r14
mov edx, 8294400
mov rdi, rax
xor esi, esi
call memset@PLT
mov qword ptr [rbx + 8], r14
mov rax, rbx
add rsp, 8
pop rbx
pop r14
ret
f2(): # @f2()
push r15
push r14
push rbx
mov edi, 24
call operator new(unsigned long)
mov r15, rax
