libcxx's tests use various C Standard Library functions that have been marked by MSVC's CRT as deprecated by Microsoft (not by ISO). libcxx's usage is cromulent (just checking with decltype to see if the functions are being dragged in by various headers as required by the Standard), so defining _CRT_SECURE_NO_WARNINGS will silence the warnings in a targeted manner. This needs to be defined before including any CRT headers. Also, make this file prettier. Fixes D29138. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@294157 91177308-0d34-0410-b5e6-96231b3b80d8
