When building constant structs, check if the resulting LLVM struct will be bigger than the record layout size and use a packed struct if that's the case. Fixes PR5108.

Issue reported on cfe-dev.

Also fixed the code to use isConstant to determine whether to generate a 
constant global, to be consistent with CodeGenModule.  This probably 
needs to be refactored to deal with C++, though.

  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

Enable the new constant struct builder by default. The old code is still in place but will be removed shortly. The new struct builder works on big endian systems.

More work on the constant struct builder, fix a couple of thinkos and add support for inserting part of a bitfield in the previous byte.

More work on the constant struct builder. We can now convert the struct to a packed struct when necessary.

llvm-svn: 77038

More work on the constant struct builder. We now try to layout all constant structs but throw away the result.
