4234f57fa0 switch TargetLowering::getConstraintType to take the entire constraint,
not just the first letter.  No functionality change.

2b81207b4b More APIntification:
* Convert the last use of a uint64_t that should have been an APInt.
* Change ComputeMaskedBits to have a const reference argument for the Mask
  so that recursions don't cause unneeded temporaries. This causes temps
  to be needed in other places (where the mask has to change) but this
  change optimizes for the recursion which is more frequent.
* Remove two instances of &ing a Mask with getAllOnesValue. Its not
  needed any more because APInt is accurate in its bit computations.
* Start using the getLowBitsSet and getHighBits set methods on APInt
  instead of shifting. This makes it more clear in the code what is
  going on.

a1689ea60e Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size
illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.

758d1bc919 Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that
they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

5b7e659e22 In the getBitsSet function, don't optimize for a common case that is
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.
