Shoot. I only updated the branch with the same name in https://github.com/llvm/llvm-project. I created this PR from my personal's repository since it was supposed to be the last in the series. 

I created a new one at #110217, since I am planning another PR on top. Thanks for trying out and sorry for the confusion.

NB. #110217 changes the default to `FLANG_RT_ENABLE_SHARED=OFF`. This is because most linkers prioritize the shared library if available and cause any executable created using the flang driver to require `libflang_rt.so`. Eventually, we should add an equivalent to `-static-libgcc` and `-static-libgfortran` to the Flang driver.
