[flang] Port test_any.sh tests to FileCheck: Hand port getsymbols tests

test_any.sh's FileCheck accepts the CHECK line matches in any order while
FileCheck checks in strict order. Re-order the CHECK lines to source code
order - they come from an ordered datastructure.

Some CHECK lines are sensitive to line number which are fixed up manually.

getsymbols02 had multiple test inputs which had their own EXEC lines.
Consolidate these together in one file.
