llvm function is marked nounwind
This fixes cases where an invoke is emitted, despite the called llvm
function being marked nounwind, because ConstructAttributeList failed to
add the attribute to the attribute list. llvm optimization passes turn
invokes into calls and optimize away the exception handling code, but
it's better to avoid emitting the code in the front-end if the called
function is known not to raise an exception.

If we're going to assume references are dereferenceable, we should also
assume they're aligned: otherwise, we can't actually dereference them.

Summary:
Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults
to -fsemantic-interposition).
Users need to specify -fsemantic-interposition to get semantic
interposition behavior.
Semantic interposition is currently a best-effort feature. There may
still be some cases where it is not handled well.

If local allocator was declared and used in the allocate clause, it was
not captured in inner region. It leads to a compiler crash, need to
capture the allocator declarator.
