[binutils-gdb] Pass readable_regcache to gdbarch method read_pc


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=c113ed0ca238bbcbc161f059ffe9b064e3ece333

commit c113ed0ca238bbcbc161f059ffe9b064e3ece333
Author: Yao Qi <yao.qi@linaro.org>
Date:   Wed Feb 21 11:20:03 2018 +0000

    Pass readable_regcache to gdbarch method read_pc
    
    We can pass readable_regcache to gdbarch method read_pc where it is
    allowed to do read from regcache.

    	* avr-tdep.c (avr_read_pc): Change parameter type to
    	readable_regcache.
    	* gdbarch.sh (read_pc): Likewise.
    	* gdbarch.c: Re-generated.
    	* gdbarch.h: Re-generated.
    	* hppa-tdep.c (hppa_read_pc): Change parameter type to
    	readable_regcache.
