IMPALA-6002: Add a LLVM diagnostic handler for LLVM linker errors

Currently if llvm encounters an error it calls exit() and this kills
the impalad process. This patch adds a diagnostic handler that llvm
can use to pass the error up to impala instead of crashing it.

Testing:
Added a test which induces an error in llvm and makes sure that its
passed up to impala code and handled correctly.
