It turns out most of the thumb2 instructions are not allowed to touch SP. The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing.
...
This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time.
This fixes PR4659 and PR4682.

Fix several fixmes and clean up code by sinking *all* section
...
creation activity into the target-specific subclasses of TLOF.
Before this, globals with explicit sections could be created by
the base class.
1. make getOrCreateSection protected, add a new getExplicitSectionGlobal
pure virtual method to assign sections to globals with a specified
section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is
now just a static method for ELF.
4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16.
They are now all detangled and understandable, woo! :)

When we encounter a dependent type that was parsed before we know that
...
we were going to enter into the scope of a class template or class
template partial specialization, rebuild that type so that it can
refer to members of the current instantiation, as in code like
template<typename T>
struct X {
typedef T* pointer;
pointer data();
};
template<typename T>
typename X<T>::pointer X<T>::data() { ... }
Without rebuilding the return type of this out-of-line definition, the
canonical return type of the out-of-line definition (a TypenameType)
will not match the canonical return type of the declaration (the
canonical type of T*).
