Log:
"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:
