Summary: It is possible for some passes to materialize a call to a libcall (ex: ldexp, exp2, etc), but these passes will not mark the call as a gc-leaf-function. All libcalls are actually gc-leaf-functions, so we change llvm::callsGCLeafFunction() to tell us that available libcalls are equivalent to gc-leaf-function calls.
