Changed names of test files to avoid Fujitsu compiler bug

The Fujitsu compilers use an older version of the Clang
parser where certain static class initializers (e.g. strings)
are put in a static initializer function stub named after
the file and class. When the first such class has identical
names in two different files where the last part of the
name is identical, this will result in clashing symbols
at link time. Working around this would require an extra
(unused) class definition in each file that would pollute the
code, so for now we merely rename the files where it occurs
and hope that the compilers will be fixed (a bug report has
been submitted).
