Target FP printing: Use floatformat_to_string in tdep code
A few tdep files use target-specific printing routines to output values in
the floating-point registers. To get rid of host floating-point code,
this patch changes them to use floatformat_to_string instead.
No functional change intended, the resulting output should look the same.
ChangeLog:
2017-10-24 Ulrich Weigand <uweigand@de.ibm.com>
* i387-tdep.c (print_i387_value): Use floatformat_to_string.
* sh64-tdep.c (sh64_do_fp_register): Likewise.
* mips-tdep.c (mips_print_fp_register): Likewise.
