We didn't consider any alignment attributes on an EnumDecl when
calculating alignment.
While we are here, ignore alignment specifications on typedef types if
one is used as the underlying type. Otherwise, weird things happen:
enum Y : int;
Y y;
typedef int __attribute__((aligned(64))) u;
enum Y : u {};
What is the alignment of 'Y'? It would be more consistent with the
overall design of enums with fixed underlying types to consider the
underlying type's UnqualifiedDesugaredType.
This fixes PR22279.

The size of the array may not be aligned according to alignment of its elements if an alignment attribute is
specified in a typedef. Fixes rdar://8665729 & http://llvm.org/PR5637.

__alignof__ operator, make sure to take into account the packed alignment
of the struct/union/class itself. Matches GCC's behavior and fixes PR6362.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
