vector<>::push_back() in:

  int foo(vector<int> &a, vector<unsigned> &b) {
    a.push_back(10);
    b.push_back(11);
  }

to two calls to the same push_back function, or fold away the two copies of
push_back() in:

  struct T { int; };
  struct S { char; };
  vector<T*> t;
  vector<S*> s;
  void f(T *x) { t.push_back(x); }
  void g(S *x) { s.push_back(x); }

but leave f() and g() separate, since they refer to two different global
variables.

Bring back VLD1q and VST1q and use them for reloading / spilling Q registers. This allows folding loads and stores into VMOVQ.

MC: Add MCAlignFragment::OnlyAlignAddress bit. This is a bit of magic that says the align fragment shouldn't contribute to the logical section size, it is will be used for cleaning up the code to handle section alignment.

MC: Add MCSectionData::AddressSize, which is the size of the address space consumed by the section. This can differ from both the section logical size, and the section size on disk (although the current code handles this without making an explicit distinction).

Fix some potential issues in the pseudo instruction expansion phase: copy implicit operands and memoperands. Also, expand instructions even if their defs are "dead" since they may have implicit kill operands.
