literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). llvm-svn: 159206
