Remove an (incorrect) compiler workaround in the __mu function. The workaround relied on rvalue references binding to non-function lvalues, while the original formulation (with std::forward) does the right thing. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@124241 91177308-0d34-0410-b5e6-96231b3b80d8
