I have measured compile time performance impact with timing check-llvm-codegen-amdgpu on the release build:

```
before the patch:           11.06s
add folding:                11.09s +0.2%
remove folding from shrink: 11.02s -0.4%
```
In general the impact smaller than run to run variance, the numbers are median time of 5 runs.
