Chris Lattner 4ac7a0ca8f reject patterns that have dead named arguments in the input pattern
this is tidier and can find bugs.

Chris Lattner 967d54ae04 reject patterns that mention a name in the destination pattern
but not in the input.  Previously, this would trigger an abort
late in the isel logic.

Anton Korobeynikov 3a639a07ea Do not infer the target type for COPY_TO_REGCLASS from dest regclass, this won't work if it can contain several types. Require explicit result type for the node for now. This fixes PR5364.
PS: It seems that blackfin usage of copy_to_regclass is completely bogus!

Bob Wilson cdfa01bf0f PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's type
inferencing.  As far as I can tell, these are equivalent to the existing
MVT::fAny, iAny and vAny types, and having both of them makes it harder
to reason about and modify the type inferencing code.

The specific problem in PR4795 occurs when updating a vAny type to be fAny
or iAny, or vice versa.  Both iAny and fAny include vector types -- they
intersect with the set of types represented by vAny.  When merging them,
choose fAny/iAny to represent the intersection.  This is not perfect, since
fAny/iAny also include scalar types, but it is good enough for TableGen's
type inferencing.

Daniel Dunbar 6f5cc82686 Fix non-determinism in DAGISel emitter.
- This manifested as non-determinism in the .inc output in rare cases (when two
   distinct patterns ended up being equivalent, which is rather rare). That
   meant the pattern matching was non-deterministic, which could eventually mean
   the code generator selected different instructions based on the arch.

 - It's probably worth making the DAGISel ensure a total ordering (or force the
   user to), but the simple fix here is to totally order the Record* maps based
   on a unique ID.

 - PR4672, PR4711.

Yay:

Bob Wilson 36e3e668be Add a new "SDTCisVec" SDTypeConstraint. This complements the vAny type.
There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.
