Fix llvm backend to work with latest inkwell.

Browse Source 
cargo update to pick up latest inkwell branch commit.

Add lifetime annotations to Module which now takes a lifetime, and more lifetime annotations across intrinsics.rs.

Add <'ctx> to missing places in CtxType and Intrinsics. Remove it from reference bindings.

Use ManuallyDrop to ensure that context's members are dropped before the Context.
