Continuation line ICE

[JFH]

Ifx 2025.2 gave an ICE with this program that ran happily with gfortran and AMD flang. Its line 1 has a statement number, continuation mark, and comment.
```
1 & ! file badcontinuation.f90
write(*,*)'Hello World 1'
end program
```
Output from other compilers:
```
Hello World 1
```
Output from ifx 2025.2:

@JFH thank you for reporting this. 
I do see this bug in ifx versions up to and including 2025.2.0.
We have been correcting some code in continuation line parsing.  It appears our code main branch does not error out with ICE for this example.  This branch will become 2025.3.0.  Because of this I won't open a bug report, it appears we already have a fix.
