Patch fixes an obscure bug when 'used' attribute is applied to
variables in ObjC's Next runtime mode. Next runtime also implicitly applies
'used' attribute on some of its meta-data. This results in two
'llvm.used' arrays to be generated, and one of them is renamed to
'llvm.used1'.

Sink the BuiltinInfo object from ASTContext into the

Add code for emitting C++ destructors. Not used yet.

Handle the edge case of a weak function with incomplete type correctly.
Found by code inspection; I haven't seen this in real-world code.

A C++ member function always has either weak linkage (if it's inline or defined inline) or strong linkage (other cases).

get emitted.

When defining a function whose type has no prototype, make an effort
to go back and clean up existing uses of the bitcasted function. This
is not just an optimization: it is required for correctness to get
always inline functions to work, see testcases in function-attributes.c.
