Test: https://github.com/fujitsu/compiler-test-suite/blob/main/Fortran/0394/0394_0031.f90
This test used to compile quickly (less than 2 min), even with -g, but now takes "forever" to compile. (I waited for more than 20 min, then killed compilation.)
`flang -c 0394_0031.f90` compiles quickly.
`flang -c -g 0394_0031.f90` compiles "forever"
Compiler used:
```
$ flang --version
flang version 20.0.0git (https://github.com/llvm/llvm-project.git 630177ccdde44b0dd8faa13b34002d15c4b0af8d)
Target: x86_64-unknown-linux-gnu
```
It was pointed out to me that this slow-down may be related to https://github.com/llvm/llvm-project/pull/122770
