Volodymyr Sapsai 93317d82da [CodeGen] Fix calling llvm.var.annotation outside of a basic block. 
When we have an annotated local variable after a function returns, we
generate IR that fails verification with the error

> Instruction referencing instruction not embedded in a basic block!

And it means that bitcast referencing alloca doesn't have a parent basic
block.

Fix by checking if we are at an unreachable point and skip emitting
annotations. This approach is similar to the way we emit variable
initializer and debug info.
