AMDGPU has some buffer intrinsics which theoretically could use
this. Some of the generated tables include the 3 and 4 element vector
versions of these rounded to 64-bits, which is ambiguous. Add these to
help the table disambiguate these.
Assertion change is for the path odd sized vectors now take for R600.
v3i16 is widened to v4i16, which then needs to be promoted to v4i32.

Some out of tree backend require larger vector type. Since maintaining the changes out of tree is difficult due to the many manual changes needed when adding a new type we are adding it even if no backend currently use it.

AMDGPU would like to use these MVTs.

Implements PR34259
Intrinsics.h is a very popular header. Most LLVM TUs care about things
like dbg_value, but they don't care how they are implemented. After I
split these out, IntrinsicImpl.inc is 1.7 MB, so this saves each LLVM TU
from scanning 1.7 MB of source that gets pre-processed away.
It also means we can modify intrinsic properties without triggering a
full rebuild, but that's probably less of a win.
I think the next best thing to do would be to split out the target
intrinsics into their own header. Very, very few TUs care about
target-specific intrinsics. It's very hard to split up the target
independent intrinsics like llvm.expect, assume, and dbg.value, though.

Allows preserving MachineMemOperands on intrinsics
through selection. For reasons I don't understand, this
is a static property of the pattern and the selector
deliberately goes out of its way to drop if not present.
Intrinsics already inherit from SDPatternOperator allowing
them to be used directly in instruction patterns. SDPatternOperator
has a list of SDNodeProperty, but you currently can't set them on
the intrinsic. Without SDNPMemOperand, when the node is selected
any memory operands are always dropped. Allowing setting this
on the intrinsics avoids needing to introduce another equivalent
target node just to have SDNPMemOperand set.

Adds scalable vector machine value types, and updates
the switch statements required for tablegen.

Currently you can't specify node properties like commutativity on
a PatFrag. If you want to create a PatFrag on a commutative node
with a hasOneUse predicate, this enables you to specify that the
PatFrag is also commutable.

Summary:
Add the necessary plumbing so that llvm_token_ty can be used as an
argument/return type in intrinsic definitions and correspondingly require
TokenTy in function types. TokenTy is an opaque type that has no target
lowering, but can be used in machine-independent intrinsics. It is
required for the upcoming llvm.eh.padparam intrinsic.

The v1i128 type is needed for the quadword add/substract instructions introduced
in POWER8. Futhermore, the PowerPC ABI specifies that parameters of type v1i128
are to be passed in a single vector register, while parameters of type i128 are
passed in pairs of GPRs. Thus, it is necessary to be able to differentiate
between v1i128 and i128 in LLVM.

In historical reason, tblgen is not strictly required to be free from memory leaks.
For now, I mark them as XFAIL, they could be fixed, though.
