263bd9abe2 fix a type contradition: XCoreISD::RETSP has one argument, not zero.

caa8870fe0 finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
and those derived from them.  These are obnoxious because
they were written as: PatLeaf<(bitconvert).  Not having an
argument was foiling adding better type checking for operand
count matching up with what was required (in this case,
bitconvert always requires an operand!)

matchable: it seems like it would always constant fold.

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.

of the previous load - it's usually important.  For example, we don't want
to blindly turn an unaligned load into an aligned one.

2ad4aca8b2 If we mark clean-ups as clean-ups, then it could break when inlining through an
'invoke' instruction. You will get a situation like this:

bb:
  %ehptr = eh.exception()
  %sel = eh.selector(%ehptr, @per, 0);

...

bb2:
  invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

lpad:
  ...

The unwinder will see the %sel call as a clean-up and, if it doesn't have a
catch further up the call stack, it will skip running it. But there *is* another
catch up the stack -- the catch for the %lpad. However, we can't see that. This
is fixed in code-gen, where we detect this situation, and convert the "clean-up"
selector call into a "catch-all" selector call. This gives us the correct
semantics.

N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand).

Add a parent class N3Vf which requires passing a Format argument and which the
N3V class is modified to inherit from.  N3V class represents the "normal"
3-Register NEON Instructions with N3RegFrm.

Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift
Instructions and replace 8 invocations with it.
