Lang Hames 2f17824463 [ORC] Don't call isa<> on a null value. 
This should fix the recent builder failures in the test-global-ctors.ll testcase.

Lang Hames 6a94134b11 [ORC] Add LLJIT and LLLazyJIT, and replace OrcLazyJIT in LLI with LLLazyJIT. 
LLJIT is a prefabricated ORC based JIT class that is meant to be the go-to
replacement for MCJIT. Unlike OrcMCJITReplacement (which will continue to be
supported) it is not API or bug-for-bug compatible, but targets the same
use cases: Simple, non-lazy compilation and execution of LLVM IR.

LLLazyJIT extends LLJIT with support for function-at-a-time lazy compilation,
similar to what was provided by LLVM's original (now long deprecated) JIT APIs.

This commit also contains some simple utility classes (CtorDtorRunner2,
LocalCXXRuntimeOverrides2, JITTargetMachineBuilder) to support LLJIT and
LLLazyJIT.

Both of these classes are works in progress. Feedback from JIT clients is very
welcome!

Lang Hames 5721ee48a2 [ORC] Re-apply r327566 with a fix for test-global-ctors.ll. 
Also clang-formats the patch, which I should have done the first time around.

Lang Hames b1cd98a18d [Orc] Add support classes for inspecting and running C++ static ctor/dtors, and 
use these to add support for C++ static ctors/dtors to the Orc-lazy JIT in LLI.

Replace the trivial_retval_1 regression test - the new 'hello' test is covering
strictly more code.
