Fix invalid read of literal (anonymous) structure names on assertion builds.

Bug: 22926131

This change adds support for using libbcc with an assertion-enabled
build of LLVM via the FORCE_BUILD_LLVM_DISABLE_NDEBUG define. It also
restricts the use of getName() on literal structures. Although a
separate patch to frameworks/rs that makes our RS object types not just
typedefs of anonymous structs can fix this safely going forward, our
release builds will need to be able to read legacy bitcode that uses
anonymous literal structure types. Thus, we need the ability to call
getName() on all structures for release builds. In the case of assertion
builds, we will enforce that we are using the updated compiler + headers
so that the structures are not anonymous. If an older compiler + headers
are used in the host compile, the bcc compilation will fail with an
appropriate error message.
