  Changed paths:
    M flang/lib/Evaluate/fold-integer.cpp
    M flang/test/Evaluate/rewrite01.f90

  Log Message:
  -----------
  Folding in the front end was replacing calls to LEN and dropping
arguments even in situations where the arguments are required to compute
the LEN value at runtime.

Add tests.
