6269b6c9cb remove a pattern with no testcase that doesn't appear to be 
matchable: it seems like it would always constant fold.

0a00ed98f1 fix integer negates to use the proper type for the zero vectors, 
this also depends on the new "bitconvert dropping" behavior just
added to tblgen.

7a0eb91b4c teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4), 
transforming it into (add (i32 GPR), 4).  This allows us to write type
generic multi patterns and have tblgen automatically drop the bitconvert
in the case when the types align.  This allows us to fold an extra load
in the changed testcase.

b26fdcb48b fix vnot matching to explicitly specify the type of the 
input to be v8i8 or v16i8, which buildvectors get canonicalized to.

This allows the patterns that were previously using a bare 'vnot' to
match, before they couldn't.

ec243474bc Oops, r98447 dropped the reference to ForwardType in the wrong place in 
Type::destroy(), so it got skipped for FunctionTypes, StructTypes, and
UnionTypes.  This fixes the resulting leaks in test/Feature/opaquetypes.ll and
test/Integer/opaquetypes_bt.ll.

b4a52b04bd fix a long standing fixme, which required fixing a bunch of other 
issues to get here.  We now trim the result type list of the
CompleteMatch or MorphNodeTo operation to be the same size as the
thing we're matching.  this means that if you match (add GPR, GPR)
with an instruction that produces a normal result and a flag that
we now trim the result in tblgen instead of having to do it 
dynamically.  This exposed a bunch of inconsistencies in result
counting that happened to be getting lucky since the days of the
old isel.
