[PATCH] D64082: [MemFunctions] Add microbenchmarks for memory functions.

[Chris Matthews via llvm-commits]

This seems to have broken the test-suite for me on some older systems.

MicroBenchmarks/MemFunctions/main.cpp:34:10: error: unknown type name 'constexpr'
  static constexpr size_t kMaxBufSizeBytes = 4096;
         ^

Could your cmake maybe explicitly set the C++ version?
