Fredrik Roubert b4b2378931 ICU-20601 Wrap ICU test compound macros in do { } while. 
This does the same for the ICU test code as was done for the
public ICU API in commit 480bec3ea6.

/**
* Test for UObject, currently only the classID.
*
* Usage
* TESTCLASSID_NONE_DEFAULT(Foo)
* -- Foo is expected to not support "poor man's RTTI".
* Beginning with ICU 4.6, we only use compiler RTTI in new class hierarchies.
*
* TESTCLASSID_NONE_CTOR(Foo, (1, 2, 3, status))
* -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_CTOR().
*
* TESTCLASSID_NONE_FACTORY(Foo, (1, 2, 3, status))
* -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_FACTORY().
*
* TESTCLASSID_ABSTRACT(Bar)
* -- Bar is expected to be abstract. Only the static ID will be tested.
*
* TESTCLASSID_DEFAULT(Foo)
* -- Foo will be default-constructed.
*
* TESTCLASSID_CTOR(Foo, (1, 2, 3, status))
* -- Second argument is (parenthesized) constructor argument.
* Will be called as: new Foo ( 1, 2, 3, status) [status is tested]
*
* TESTCLASSID_FACTORY(Foo, fooCreateFunction(status) )
* -- call fooCreateFunction. 'status' will be tested & reset
*
* TESTCLASSID_FACTORY_HIDDEN(class, factory)
* -- call factory. Class is not available from a header.
* 'status' will be tested & reset. This only tests uniqueness.
