In our recent discussion we are aiming to make LLDB registers exchange minimum possible information in qRegisterInfo or XMl register descriptions.
For SVE registers Z registers are catagorized as primary registers and need not have any infomration on its pseudo registers. Rather only the pseudo registers should have the information on which primary register they belong to.
This patch invalidate_regs list from Z registers and will mitigate its impact on SVE resize patch in a follow up update.
