r188663 - XCore target: correct test layout

Hi Dmitri,

No reason, apart from ignorance.

I've searched briefly for documentation, but did not come across anything that explains the mechanism.
Could you enlighten me?
Is 'clang' the driver, which in turn will call the C compiler 'cc1' (assuming a .c file)?
As we know we want the C compiler we can call it directly - removing an unnecessary step.
Does the test suite will convert 'clang_cc1' into 'clang -cc1'?

Also, would I be right in thinking that -O0 will be the default, so this can be left off too?

Thus, I should use:
    // RUN: %clang_cc1 -target xcore -o - -emit-llvm -S %s | FileCheck %s

However, the driver test should remain:
    // RUN: %clang -target xcore %s -### -o %t.o 2>&1 FileCheck %s

I'll await your reply before making changes.
Thank you

Why not %clang_cc1?
