[NFC] Explicitly add -std=c++14 option to tests that rely on the C++14 default When Clang/LLVM is built with the CLANG_DEFAULT_STD_CXX CMake macro that sets the default standard to something other than C++14, there are a number of lit tests that fail as they rely on the C++14 default. This patch just adds the language standard option explicitly to such test cases.

Switch to gnu++14 as the default dialect. This is C++14 with conforming GNU extensions. llvm-svn: 320250 2017-12-09 20:09:54 +08:00			`float a = 1.0h; // expected-error{{no matching literal operator for call to 'operator""h' with argument of type 'long double' or 'const char *', and no matching literal operator template}}`
[OpenCL] Added half type literal with suffix h. OpenCL Extension v1.2 s9.5 allows half precision floating point type literals with suffices h or H when cl_khr_fp16 is enabled. Example: half x = 1.0h; Patch by Liu Yaxun (Sam)!

Recommit "Add _Float16 as a C/C++ source language type" This is a recommit of r312781; in some build configurations variable names are omitted, so changed the new regression test accordingly. llvm-svn: 312794 2017-09-08 23:15:00 +08:00
