"Use" lambda captures which are otherwise only used in asserts. NFC

Summary: The LLVM coding standards recommend "using" values that are only needed by asserts: http://llvm.org/docs/CodingStandards.html#assert-liberally Without this change, LLVM cannot bootstrap with -Werror as the second stage fails with this new warning: https://reviews.llvm.org/rL291905 See also the previous fixes: https://reviews.llvm.org/rL291916 https://reviews.llvm.org/rL291939 https://reviews.llvm.org/rL291940 https://reviews.llvm.org/rL291941 Reviewers: rsmith Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D28695 llvm-svn: 291957
