Setup llvm-symbolizer when running the tests with sanitizers

Mark more tests as UNSUPPORTED with ASAN and MSAN.

These tests fail for 2 reasons when using ASAN and MSAN.
1. If allocator_may_return_null=0 they will fail because null is returned
   or an exception is thrown.
2. When allocator_may_return_null=1 the new_handler is still not called. This
   results in an assertion failures.

Split string capacity test into two parts and mark one part as UNSUPPORTED when using sanitizers.

The test is split such that:
- max_size.pass.cpp tests that string::resize() fails to allocator for max_size
  and max_size -1
- over_max_size.pass.cpp tests that string::resize() throws a length error for
  max_size + 1

The test was split into two because max_size.pass.cpp cannot pass with 
sanitizers but over_max_size.pass.cpp can.

[libcxx] Fix vector annotator size increase in `vector::insert(pos, count, value)`

Summary:
The size of the vector is being increased by `__n` during the call to `__move_range` and not by 1.
This fixes a test failure in `containers/sequences/vector/vector.modifiers/insert_iter_size_value.pass.cpp` when using ASAN.

[libcxx] Fix memory leak in strstream tests.

Summary: The strstream function `str()` sets `freeze(true)`. When `freeze` is true the destructor is not allowed to free any dynamically allocated memory. The memory leak causes ASAN to fail on these tests. To ensure memory is deallocated `strstream.freeze(false)` is called at the end of the tests.
