Emit guard variables for any weak global that has a run-time

initializer. Previously, we only used guard variables for weak static
data members. Fixes <rdar://problem/9692249>.

When laying out bases in, always try the "base subobject" LLVM type. If it
...
turns out that a field or base needs to be laid out in the tail padding of
the base, CGRecordLayoutBuilder::ResizeLastBaseFieldIfNecessary will convert
it to an array of i8.
I've audited the new test results to make sure that they are still valid. I've
also verified that we pass a self-host with this change.
This (finally) fixes PR5589!

Template static data members can have weak_odr linkage, not just

weak linkage. Also, fix a problem where global weak variables
with non-trivial initializers were getting guard variables, or at
least were checking for them and then crashing.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- 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).
