constant fold the operands if possible and create an instruction otherwise:
* ``LLVMConstExtractValue``
+* Refactor compression namespaces across the project, making way for a possible
+ introduction of alternatives to zlib compression in the llvm toolchain.
+ Changes are as follows:
+ * Remove crc32 from zlib compression namespace, people should use the ``llvm::crc32`` instead.
+ * Relocate the ``llvm::zlib`` namespace to ``llvm::compression::zlib``.
+ * Code that explictly needs ``zlib`` compression (IE zlib elf debug sections) should use ``llvm::compression::zlib``.
+ * Code interfacing with compressed profile data should use ``llvm::compression::profile``.
+ * Code interfacing with compressed serialized data should use ``llvm::compression::serialize``.
+ * Other code should use ``llvm::compression::tooling``.
