Siva Chandra Reddy af1315c28f [libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.
This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.
