21c4dc7997 std::optional::value => operator*/operator->
value() has undesired exception checking semantics and calls
__throw_bad_optional_access in libc++. Moreover, the API is unavailable without
_LIBCPP_NO_EXCEPTIONS on older Mach-O platforms (see
_LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS).

This fixes clang.

a5f1262332 [VE] v256.32|64 gather|scatter isel and tests
This adds support for v256.32|64 scatter|gather isel.  vp.gather|scatter
and regular gather|scatter intrinsics are both lowered to the internal
VVP layer.  Splitting these ops on v512.32 is the subject of future
patches.

7d926b7177 [VE] LEGALAVL and staged VVP legalization
The new LEGALAVL node annotates that the AVL refers to packs of 64bit.
We use a two-stage lowering approach with LEGALAVL:

First, standard SDNodes are translated into illegal VVP layer nodes.
Regardless of source (VP or standard), all VVP nodes have a mask and AVL
parameter. The AVL parameter refers to the element position (just as in
VP intrinsics).

Second, we legalize the AVL usage in VVP layer nodes. If the element
size is < 64bit, the EVL parameter has to be adjusted to refer to packs
of 64bits.  We wrap the legalized AVL in a LEGALAVL node to track this.
