8586bfd85d @llvm.sqrt isn't really close enough to C's sqrt to justify emitting calls 
to the intrinsic, even when math-errno is off.

Fixes rdar://problem/7828230 by falling back on the library function.

fdb76ccfb4 a ridiculous amount of propagation through the backend later, 
have the code generate slap a srcloc metadata on inline asm nodes.
This allows us to diagnose invalid inline asms with such nice 
diagnostics as:

<inline asm>:1:2: error: unrecognized instruction
        abc incl    %eax
        ^
asm.c:2:12: note: generated from here
  __asm__ ("abc incl    %0" : "+r" (X));
           ^
2 diagnostics generated.

dc406b8e92 IRgen: Move BitField LValues to just hold a reference to the CGBitFieldInfo. 
- Unfortunately, this requires some horrible code in CGObjCMac which always
   allocats a CGBitFieldInfo because we don't currently build a proper layout
   for Objective-C classes. It needs to be cleaned up, but I don't want the
   bit-field cleanups to be blocked on that.

8c7f981833 IRgen/Obj-C: Eliminate FindIvarInterface, now that ivar's are in the right DeclContexts (-2 FIXMEs). We still have an annoying linear scan + hidden dependency on how Obj-C layout is done. 
- This is also an algorithmic improvement in IRgen for Obj-C, although it probably doesn't matter in practice.

45cf7e3d2a Rework our handling of copy construction of temporaries, which was a 
poor (and wrong) approximation of the actual rules governing when to
build a copy and when it can be elided.

The correct implementation is actually simpler than the
approximation. When we only enumerate constructors as part of
initialization (e.g., for direct initialization or when we're copying
from a class type or one of its derived classes), we don't create a
copy. When we enumerate all conversion functions, we do create a
copy. Before, we created some extra copies and missed some
others. The new test copy-initialization.cpp shows a case where we
missed creating a (required, non-elidable) copy as part of a
user-defined conversion, which resulted in a miscompile. This commit
also fixes PR6757, where the missing copy made us reject well-formed
code in the ternary operator.

This commit also cleans up our handling of copy elision in the case
where we create an extra copy of a temporary object, which became
necessary now that we produce the right copies. The code that seeks to
find the temporary object being copied has moved into
Expr::getTemporaryObject(); it used to have two different
not-quite-the-same implementations, one in Sema and one in CodeGen.

Note that we still do not attempt to perform the named return value
optimization, so we miss copy elisions for return values and throw
expressions.
