ICU-20797 fix UBS compilation error and UBS in test code

Two issues here:

- fix 2 build issue in i18n when compiling with clang++ -fsanitize=undefined
the following two symbols were not exported (and they should be):
  typeinfo for icu::CollationCacheEntry
  typeinfo for icu::numparse::impl::CodePointMatcher

- remove undefined behavior warning in NumberFormatTestTuple.. minor, but very annoying
when repeated many times during every test run. Tends to mask real errors.

> numberformattesttuple.cpp:319:5: runtime error: member access within null pointer of type 'NumberFormatTestTuple'
