This adjusts the tests for the difference between line endings on
different platforms. Windows uses CRLF while most Unicies use LF. This
was exposed during the update to the new LLVM snapshot.
This converts the instances of the pattern for which we have a proper
substitution in lit. This will make it easier to replace it
appropriately with Windows equivalents.
We were implicitly assuming that a function reference could only happen
in an expression, ignoring the case of
import func Module.fooFunc
For now, this doesn't actually add the reference to the index because
initCallRefIndexSymbol doesn't allow references without a parent
expression. We can look at adding the reference, or maybe doing
something special to the import itself separately.
