aefbc83e95 target-mips: simplify exception generation

007ac6faed target-mips: fix call to check_*() functions 
check_*() functions may in fine call generate_exception(), which ends
by a call to tcg_gen_exit_tb(). As a consequence, we have to make sure
that no TCG temp variables are crossing a check_*() function.

1b530a6dfc Add new command line option -singlestep for tcg single stepping. 
This replaces a compile time option for some targets and adds
this feature to targets which did not have a compile time option.

Add monitor command to enable or disable single step mode.

Modify monitor command "info status" to display single step mode.
