[compiler-rt] Disable fuzzer large.test when LLVM_ENABLE_EXPENSIVE_CHECKS=ON

This test is timing out on Green Dragon http://green.lab.llvm.org/green/job/clang-stage1-cmake-RA-expensive/
and looks like it's not executed on other bots with expensive checks
enabled
http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-ubuntu
http://lab.llvm.org:8011/builders/llvm-clang-x86_64-expensive-checks-win

The test times out at the C++ source file takes too long to build (2+ hours on my machine), as
clang spends a lot of time in IR/MIR verifiers.
