It indeed generates better code. However, it requires that I duplicate the
function body, which can be hard at times (consider f == std::transform and "if
(*b != 0) { *b = g(*b); }" as a lambda input.

Right doing shrink wrapping like that is "hard" really and someone would need
to add a full infrastructure for this. I doubt it will

I expect something like this:
f(int*, int*):
cmp rdi, rsi
je .L10
.L4:
cmp DWORD PTR [rsi], 0
jne .L14
.L3
add rsi, 4
cmp rsi, rdi
