As described in the PR, we can create a PHI node in einline that has no

That can cause ICE in devirtualization and should be thus handled.

The code in fold_comparison calls save_expr on an expression and then tries to
set a location of the expression. But since save_expr calls fold, it can
produce an integer constant, so we must be more careful when setting its
location. In this case we had
