Subject: Force c++14 when running tests on Windows.
X-Git-Tag: llvmorg-4.0.0-rc1~9862
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=471932de24b9445efc512e6bb7160099af4ad997;p=platform%2Fupstream%2Fllvm.git

Force c++14 when running tests on Windows.

VS 2015 and higher begin making use of c++14 in their standard
library headers.  As such, -std=c++11 makes it so you can't compile
trivial programs.  Bump this to -std=c++14 when this situation is
detected.
