Bug 143374 – FTL JIT tests should fail if LLVM library isn't available

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

Now run-javascriptcore-tests --ftl-jit tests pass if libllvmForJSC.so isn't available.
It isn't good that JSC silently falls back to non FTL path, because we can easily 
think that FTL is working well and all tests pass. ( It is related to bug143372 . )

Additionally now we can run FTL tests if we built JSC with disabled FTL.
It would be good to get error in this case too.

I think JSC should crash with an error message if we execute it with
run-javascriptcore-tests and fall back to non FTL path in production code.

I'm going to fix it later in a separated bug.
