f82e1e66ce And an FoldingSetImpl::NodeID::AddInteger overload for int64_t, to avoid 
ambiguity.

92dfe2001e Remove isReg, isImm, and isMBB, and change all their users to use 
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent,
and more popular.

miscompilation of 188.ammp.  Reject select and bitcast in

85dbe1a1d2 Initial support for multi-result patterns: 
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.

3f6eb7419d Add APInt interfaces to APFloat (allows directly

double interfaces where appropriate.

d50dc73b89 Two ParamAttrsVectors which differ by a permutation 
of their elements do not yield the same ParamAttrsList,
though they should.  On the other hand, everyone seems
to pass such vectors with elements ordered by increasing
index, so rather than sorting the elements simply assert
that the elements are ordered in this way.
