98dc202be0 Fix a gcc warning:
'class llvm::DAGDeltaAlgorithm' has virtual functions and accessible non-virtual destructor

Not sure if this is the best solution, but this class has state and some of the
classes that inherit from it also do, so it looks appropriate.

d847124211 Thumb2 IT blocks are fairly expensive. When there are multiple selects using
the same condition, it's important to make sure they are scheduled together
to avoid forming multiple IT blocks. I'm adding a pre-regalloc pass that forms
IT blocks early (by re-scheduling instructions and split basic blocks) to
attempt to fix this. This is not turned on by default since I am not sure this
is the right fix.

Another issue is llvm selects are modeled as two-address conditional moves.
This can be very bad when the copies before the conditional moves are not
coalesced away. Teach IT formation pass to move the copies above the IT block
(when legal) to avoid breaking the IT block.

09712b57ce Incremental improvement to the handling of the x86 "Jump if rCX Zero"
instruction.  Added the 64-bit version "jrcxz" so it is recognized and also
added the checks for incorrect uses of "jcxz" in 64-bit mode and "jrcxz" in
32-bit mode.  Still to do is to correctly handle the encoding of the
instruction adding the Address-size override prefix byte, 0x67, when the width
of the count register is not the same as the mode the machine is running in.
Which for example means the encoding of "jecxz" depends if you are assembling
as a 32-bit target or a 64-bit target.

- change isShuffleMaskLegal to show that all shuffles with 32-bit and 64-bit
  elements are legal
- the Neon shuffle instructions do not support 64-bit elements, but we were
  not checking for that before lowering shuffles to use them
- remove some 64-bit element vduplane patterns that are no longer needed
