This change adds GLSLANG_EXPORT in a couple more places, as well as adding a new symbol visibility annotation GLSLANG_EXPORT_FOR_TESTS which is defined the same as GLSLANG_EXPORT but documents the intention that the symbols marked with it are only meant to be used by glslang's test suite and do not form part of the public API and are thus not subject to ABI stability guarantees.
