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.

overly long ints, e.g. i96, into pieces at PHIs

Generate better code for v16i8 shuffles on SSE2 (avoids stack)
Generate pshufb for v8i16 and v16i8 shuffles on SSSE3 where it is fewer uops.
Document the shuffle matching logic and add some FIXMEs for later further
cleanups.

Revert the part of 64623 that attempted to align the source in a
...
memcpy to match the alignment of the destination. It isn't necessary
for making loads and stores handled like the SSE loadu/storeu
intrinsics, and it was causing a performance regression in
MultiSource/Applications/JM/lencod.
The problem appears to have been a memcpy that copies from some
highly aligned array into an alloca; the alloca was then being
assigned a large alignment, which required codegen to perform
dynamic stack-pointer re-alignment, which forced the enclosing
function to have a frame pointer, which led to increased spilling.

Implement "superhero" strength reduction, or full strength
...
reduction of address calculations down to basic pointer arithmetic.
This is currently off by default, as it needs a few other features
before it becomes generally useful. And even when enabled, full
strength reduction is only performed when it doesn't increase
register pressure, and when several other conditions are true.
This also factors out a bunch of exisiting LSR code out of
StrengthReduceStridedIVUsers into separate functions, and tidies
up IV insertion. This actually decreases register pressure even
in non-superhero mode. The change in iv-users-in-other-loops.ll
is an example of this; there are two more adds because there are
two fewer leas, and there is less spilling.

Use a sign-extend instead of a zero-extend when promoting a
...
trip count value when the original loop iteration condition is
signed and the canonical induction variable won't undergo signed
overflow. This isn't required for correctness; it just preserves
more information about original loop iteration values.
Add a getTruncateOrSignExtend method to ScalarEvolution,
following getTruncateOrZeroExtend.

Add support to the JIT for true non-lazy operation. When a call to a function
...
that has not been JIT'd yet, the callee is put on a list of pending functions
to JIT. The call is directed through a stub, which is updated with the address
of the function after it has been JIT'd. A new interface for allocating and
updating empty stubs is provided.
Add support for removing the ModuleProvider the JIT was created with, which
would otherwise invalidate the JIT's PassManager, which is initialized with the
ModuleProvider's Module.
Add support under a new ExecutionEngine flag for emitting the infomration
necessary to update Function and GlobalVariable stubs after JITing them, by
recording the address of the stub and the name of the GlobalValue. This allows
code to be copied from one address space to another, where libraries may live
at different virtual addresses, and have the stubs updated with their new
correct target addresses.

Fix a corner case in the new indvars promotion logic: if there
...
are multiple IV's in a loop, some of them may under go signed
or unsigned wrapping even if the IV that's used in the loop
exit condition doesn't. Restrict sign-extension-elimination
and zero-extension-elimination to only those that operate on
the original loop-controlling IV.

The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.
