deprecated_grub_regcache_for_registers. * values.c: Include "regcache.h". (value_being_returned): Update. Use deprecated_grub_regcache_for_registers to extract the register buffer address. * value.h (value_being_returned): Change ``retbuf'' parameter to a ``struct regcache''. * Makefile.in (values.o): Add dependency on $(regcache_h). * inferior.h (run_stack_dummy): Change type of second parameter to a ``struct regcache''. * valops.c (hand_function_call): Change type of retbuf to ``struct regcache''. Allocate using regcache_xmalloc, clean using make_cleanup_regcache_xfree. * infcmd.c (run_stack_dummy): Update. Use regcache_cpu_no_passthrough instead of memcpy to copy the buffer. * regcache.c (do_regcache_xfree): New function. (make_cleanup_regcache_xfree): New function. * regcache.h (make_cleanup_regcache_xfree): Declare.
