[sdb] Avoid asserting when a cattr cannot be loaded. Fixes #21653.
[jit] Avoid taking the loader lock in mono_jit_compile_method_inner (), it shouldn't be needed any more.
[jit] Reorganize the locking in mono_jit_compile_method_inner, the domain lock already makes the code lookup+insert atomic, no need to do more work inside the jit code hash lock. Also lock jit_code_hash in mono_jit_free_method ().

[ms.build] Do not try to release threads upon finalization.
[ms.build] Fix bug #20961 - add KeepDuplicates etc. to 4.0 as internal.

Since NET_4_0 and NET_4_5 share the same ToolsVersion (4.0) there seems no
way to distinguish the appropriate framework .targets file, so I ended up
to add the missing members as internal for 4.0.
[ms.build] add some cyclic dependency related tests (some are not working).
