John McCall 9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs(). 
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

Daniel Dunbar 9996138a80 Ok, an AssertingVH definitely doesn't work for now because we free our cache after the optimizer may have hacked on the module. Use a WeakVH instead.

Nick Lewycky 41eaf0ac57 Make clang stop relying on ConstantStruct::get's default value for isPacked

Fariborz Jahanian a7fa6beb2e Starting patch to generate more specific API for objc's 
GC. Currently, new API will be generated under
clang-cc's -fobjc-newgc-api flag which will eventually
become the default. WIP.

Daniel Dunbar ff0553ec61 Fix subtle bug in generating LLVM function declarations for builtin functions. 
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

Douglas Gregor 299d76e901 Rework the way we determine whether an externally visible symbol is 
generated for an inline function definition, taking into account C99
and GNU inline/extern inline semantics. This solution is simpler,
cleaner, and fixes PR4536.
