sim/rx: move some variable declarations to the start of the block
For sim code variables still need to be declared at the start of the enclosing block. This silences a few GCC warnings. sim/rx/ChangeLog: * syscalls.c (rx_syscall): Move declaration of some variables to the start of the enclosing block. * trace.c (load_file_and_line): Likewise.
