d498e5e960 Debug Info: instead of calling addToContextOwner which constructs the context
after the DIE creation, we construct the context first.

Ensure that we create the context before we create a type so that we can add
the newly created type to the parent. Remove last use of addToContextOwner
now that it's not needed.

We use createAndAddDIE to wrap around "new DIE(". Now all shareable DIEs
should be added to their parents right after the creation.

4598b40ce6 [stackprotector] Update the StackProtector pass to perform datalayout analysis.
This modifies the pass to classify every SSP-triggering AllocaInst according to
an SSPLayoutKind (LargeArray, SmallArray, AddrOf).  This analysis is collected
by the pass and made available for use, but no other pass uses it yet.

The next patch will make use of this analysis in PEI and StackSlot
passes.  The end goal is to support ssp-strong stack layout rules.

WIP.

2b0002b579 Workaround MSVC 32-bit miscompile of getCondCodeAction.
Use 32-bit types for the array instead of 64. This should
generally be better anyway.

In optimized + assert builds, I saw a failure when a
cond code / type combination that is never set was loading
a non-zero value and hitting the != Promote assert.

It turns out when loading the 64-bit value to do the shift,
the assembly loads the 2 32-bit halves from non-consecutive
addresses. The address the second half of the loaded uint64_t
doesn't include the offset of the array in the struct. Instead
of being offset + 4, it's just + 4.

I'm not entirely sure why this wasn't observed before.
setCondCodeAction isn't heavily used by the in-tree targets,
and not with the higher valued vector SimpleValueTypes. Only
PPC is using one of the > 32 valued types, and that is probably
never used by anyone on a 32-bit MSVC compiled host.

I ran into this when upgrading LLVM versions, so I guess the
value loaded from the nonsense address happened to work out
before.

No test since I'm not really sure if / how it can be reproduced
with the current in tree targets, and it's not supposed to change
anything.
