CodeGen: support blocks on COFF targets in DLLs This extends the blocks support to support blocks with a dynamically linked blocks runtime. The previous code generation would work only for static builds of the blocks runtime. Mark the block "isa" pointers and functions as dllimport if no explicit declaration marked with __declspec(dllexport) is found. This additional check allows for the use of the functionality in the runtime library if desired. llvm-svn: 271138
