[GDBserver] Use regcache_read_pc in install_software_single_step_breakpoints
In install_software_single_step_breakpoints, we've got the regcache
of current_thread, so we don't have to bother get_pc to get pc,
instead we can get pc from regcache directly. Note that the callers
of install_software_single_step_breakpoints have already switched
current_thread to LWP.
Since the pc is got from regcache_read_pc, in the next patch, we can
get pc inside the implementation of *the_low_target.get_next_pcs and
stop passing pc to *the_low_target.get_next_pcs.
gdb/gdbserver:
2016-01-26 Yao Qi <yao.qi@linaro.org>
* linux-low.c (install_software_single_step_breakpoints): Call
regcache_read_pc instead of get_pc.
