[foreign] test failure with tip

[Sundararajan Athijegannathan]

I got a test failure with tip [foreign branch].

$panama-dev/test/jdk/java/foreign/types/partial/PartialStructsTest.java:89: error: cannot find symbol
             Recursive r = sc.allocateStruct(Recursive.class);
             ^
   symbol:   class Recursive
   location: class PartialStructsTest
$panama-dev/test/jdk/java/foreign/types/partial/PartialStructsTest.java:89: error: cannot find symbol
             Recursive r = sc.allocateStruct(Recursive.class);

2 errors
result: Failed. Compilation failed: Compilation failed


 From https://hg.openjdk.java.net/panama/dev/rev/c1b415e10db0, it seems 
like Recursive.java was not "hg add"-ed?
