Nathan Froyd fa31af0e63 target-mips: fix conditional moves off fp condition codes 
Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code.  However,
get_fp_bit returns the bit number of the condition code, not a
bitmask.  (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)

Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

aurel32 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.

aurel32 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.
