[AArch64] Preserve undef on registers when expanding CALL_RVMARKER. (#71177)
Preserve the undef flag on register operands when expanding
CALL_RVMARKER. This fixes a crash when the x0 operand is undef, e.g.
because it was poison in the input IR.

Fixes https://github.com/llvm/llvm-project/issues/68005.

++ SVE CodeGen Warnings ++

When the WARN check lines fail in the SVE codegen tests it most likely means you
have introduced a warning due to:
1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
   when the type is a scalable vector.
2. Relying upon an implicit cast conversion from TypeSize to uint64_t.

For generic code, please modify your code to work with ElementCount and TypeSize directly.
For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
Please refer to the code where those functions live for more details.
