When allocating stubs, keep track of which Functions are referencing the stub.
...
This invalidates the stubs in the resolver map when they are no longer referenced,
and should the JIT memory manager ever pick up a deallocateStub interface, the
JIT could reclaim the memory for unused stubs as well.

The DAG combiner was performing a BT combine. The BT combine had a value of -1,
...
so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it
would go through the DAG combiner again. This time it had a value of 31, which
was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong
forever.

value is an XOR of all ones.

Reuse a technique (pioneered for BasicBlocks) of superposing ilist with

its sentinel. This is quite a win when a function really has a basic block.
When the function is just a declaration (and stays so) the old way did not
allocate a sentinel. So this change is most beneficial when the ratio of
function definition to declaration is high. I.e. linkers etc. Incidentally
these are the most resource demanding applications, so I expect that the
reduced malloc traffic, locality and space savings outweigh the cost of
addition of two pointers to Function.

Fix a long-standing bug and misfeature of the disassembler: when dealing with a

stripped .bc file, it didn't make any attempt to try to reuse anonymous types.
This causes an amazing type explosion due to types getting duplicated everywhere
they are referenced and other problems.
This also caused correctness issues, because opaque types are unique for each time
they are uttered in the file. This means that stripping a .bc file could produce
a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll).

Refactor TLS code and add some tests. The tests and expected results are:
...
pic | declaration | linkage | visibility |
!pic | declaration | external | default | tls1.ll tls2.ll | local exec
pic | declaration | external | default | tls1-pic.ll tls2-pic.ll | general dynamic
!pic | !declaration | external | default | tls3.ll tls4.ll | initial exec
pic | !declaration | external | default | tls3-pic.ll tls4-pic.ll | general dynamic
!pic | declaration | external | hidden | tls7.ll tls8.ll | local exec
pic | declaration | external | hidden | X | local dynamic
!pic | !declaration | external | hidden | tls9.ll tls10.ll | local exec
pic | !declaration | external | hidden | X | local dynamic
!pic | declaration | internal | default | tls5.ll tls6.ll | local exec
pic | declaration | internal | default | X | local dynamic
The ones marked with an X have not been implemented since local dynamic is not implemented.

Introduce a new technique for merging BasicBlock with Instruction sentinel by superposition.
...
This looks dangerous, but isn't because the sentinel is accessed in special way only,
namely the Next and Prev fields of it, and these are guaranteed to exist.

Silence compiler warning about use of uninitialized variables (in reality these

Alignment values for i64 and f64 on ppc64 were wrong,
...
possibly for the reason suggested by the comment.
No wonder it didn't work very well. This unblocks
bootstrap with assertions on ppc.

The last commit was overly conservative. It's ok to reuse value that's already marked livein.

If an available register falls through to a succ block, unset the last kill. Sorry, it's impossible to reduce a sensible test case. It basically requires the moon and stars to align in order to cause a failure.
