45bf0e7aa6 tcg/loongarch64: Set vector registers call clobbered 
Because there are more call clobbered registers than
call saved registers, we begin with all registers as
call clobbered and then reset those that are saved.

This was missed when we introduced the LSX support.

da4038d2da tests/tcg: Fix the /proc/self/mem probing in the PROT_NONE gdbstub test 
The `if not probe_proc_self_mem` check never passes, because
probe_proc_self_mem is a function object, which is a truthy value.
Add parentheses in order to perform a function call.
