[self-profiling] Include the estimated size of each cgu in the profile

This is helpful when looking for CGUs where the size estimate isn't a
good indicator of compilation time.

I verified that moving the profiling timer call doesn't affect the
results.

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
