[OpenCL] Improved testing of default header. Improved some checks and moved testing of the default header in C++ mode into the Headers folder. Differential Revision: https://reviews.llvm.org/D59486 llvm-svn: 356450

// RUN: %clang -save-temps -x cl -Xclang -cl-std=CL2.0 -Xclang -finclude-default-header -emit-llvm -S -### %s 2>&1 | FileCheck %s
// CHECK-LABEL: finclude-default-header
Fix up testcase to: a) avoid actually compiling anything b) avoid depositing files in the test directory c) use a check line to make sure that we're looking for the correct behavior llvm-svn: 297917

// Make sure we don't pass -finclude-default-header to any commands other than the driver.
enable -save-temps with -finclude-defult-header Currently the two flags can not work together. To illustrate the issue, we can have an one line file a.cl contains only an empty function cat a.cl void test(){} Then use clang -v -save-temps -x cl -Xclang -cl-std=CL2.0 -Xclang -finclude-default-header -target amdgcn -S -c a.cl we will get redefinition errors for various things. The reason is that the -finclude-default-header flag is not meant to be on cc1 command other than the preprocessor. The fix is modeled after the code just below the change to filter the -finclude-default-header flag out when we are not in the preprocess phase.
