Issue: Binary size is significant increased from `1.46.0` to `1.51.0`
Labels: P-medium,T-compiler,regression-from-stable-to-stable,C-bug,I-heavy

## In Brief

Our project changed the locked `rust-toolchain` from `1.46.0` to `1.51.0`.
Then binary size (`x86_64-unknown-linux-gnu`, `release`) is significant increased (`49 MiB -> 53 MiB`, `+8.2%`).

## Details

### Size of `.strtab` section is significant increased

I used `cargo build --release` to build the same code with `rust 1.46.0` and `rust 1.51.0`.

Then I analyzed the binary with `readelf -SW target/release/program`.

I got the follow result:

### The difference between the `.strtab` sections

I don't have enough knowledge about compilation.

I just saw the `.strtab` was increased too much, so I used the follow command to read the `.strtab`: `readelf -p .strtab target/release/program`.

### Another test

I tried compiling [`tokio-rs/mini-redis`] with toolchain between 1.45.0 to 1.53.0.


<details><summary>I got the follow table:</summary>

From the above table, we could got the follow conclusions:
- Binary size is significant increased from `1.46.0` to `1.47.0`.
- Binary has the biggest size at `1.51.0`.
- Binary size at `1.53.0` is still much bigger than `1.46.0`.
