I was going to introduce a couple more lists and realized that our

linked list type relatively well defined, we are using doubly linked
lists defined on the fly for the stats and for the secondary blocks.
This CL adds a doubly linked list object, reorganizing the singly list
one to extract as much of the common code as possible. We use this
new type in the stats and the secondary. We also reorganize the list
tests to benefit from this consolidation.
There are a few side effect changes such as using for iterator loops

Summary:
Would be nice to also fix this in clang, but that looks like more work
if we want to preserve signatures in informative chunks.

[X86] Use 64-bit version of source register in LowerPATCHABLE_EVENT_CALL and LowerPATCHABLE_TYPED_EVENT_CALL
Summary:
The PATCHABLE_EVENT_CALL uses i32 in the intrinsic. This
results in the register allocator picking a 32-bit register. We
need to use the 64-bit register when forming the MOV64rr
instructions. Otherwise we print illegal assembly in the text
output.
I think prior to this it was impossible for SrcReg to be equal
to DstReg so the NOP code was not reachable.
While there use Register instead of unsigned.

[LLDB][formatters] ArgInfo::count -> ArgInfo::max_positional_args
Summary:
Move breakpoints from the old, bad ArgInfo::count to the new, better
ArgInfo::max_positional_args. Soon ArgInfo::count will be no more.
This functionality is tested in `TestFormatters.py`, `TestDataFormatterSynthVal.py`,
`TestDataFormatterSynthType.py`.
You may notice that the old code was passing 0 arguments when count was 1, and passing
1 argument when count is 2.
This is no longer necessary because max_positional_args counts the self pointer
correctly.

Summary:
We don't pattern match pairwise shuffles in SelectionDAG. So we
should only return the optimized costs if its not a pairwise

I think SLP vectorizer gives priority to non pairwise shuffle if
the cost is the same. And the look up for reduction intrinsics
passes false for the pairwise flag. So this probably has no real
effect today.

[AMDGPU] Fix Vreg_1 PHI lowering in SILowerI1Copies.
There is a minor flaw in the implementation of function lowerPhis.
This function replaces values of regclass Vreg_1 (boolean values)
involved in PHIs into an SGPR. Currently it iterates over the MBBs
and performs an inplace lowering of PHIs and fails to lower any
incoming value that itself is another PHI of Vreg_1 regclass.
The failure occurs only when the MBB where the incoming PHI value
belongs is not visited/lowered yet.
To fix this problem, collect all Vreg_1 PHIs upfront and then
perform the lowering.
