cargo test --release ignores profile.release and profile.test settings

[ferencdg]

Problem
my Cargo.toml settings

[profile.release]
overflow-checks = true

[profile.test]
overflow-checks = true

if I use cargo build --release then the -C overflow-checks is correctly passed to rustc, however cargo test --release doesn't pass the overflow-checks to rustc

Steps
see above

Possible Solution(s)

Notes

Output of cargo version:

cargo 1.54.0 (5ae8d74 2021-06-22)

When using --release, tests switch to the bench profile. There's more information about profile selection at https://doc.rust-lang.org/cargo/reference/profiles.html#profile-selection. Named profiles (tracked in #6988) will likely change that behavior to pick release since it uses a more consistent profile choice.
