tltao 18189430ab [SystemZ] Add check for INIT_UNDEF in getInstSizeInBytes (#134661) ...

Due to some optimization changes, INIT_UNDEF is making its way to
`getInstSizeInBytes` in `llvm/lib/Target/SystemZ/SystemZLongBranch.cpp`
but we do not have an exception there in the assert. Since INIT_UNDEF is
described as being similar to IMPLICIT_DEF and there is a check for
IMPLICIT_DEF, it seems logical to also add a check for INIT_UNDEF.
