[Clang][Codegen] Disable arm_acle.c test.

This test is broken by design. Clang codegen tests should not depend
on llvm middle-end behaviour, they should *only* test clang codegen.
Yet this test runs whole optimization pipeline.
I've really tried to fix it, but there isn't just a few things
that depend on passes, but everything there does.
