* amd64-tdep.c (amd64_pseudo_register_read_value): Rename
	from amd64_pseudo_register_read.  Change arguments.  Call
	mark_value_bytes_unavailable when needed.
	(amd64_init_abi): Use set_gdbarch_pseudo_register_read_value, not
	set_gdbarch_pseudo_register_read.
	* sentinel-frame.c (sentinel_frame_prev_register): Use
	regcache_cooked_read_value.
	* regcache.h (regcache_cooked_read_value): Declare.
	* regcache.c (regcache_cooked_read_value): New function.
	(regcache_cooked_read): Call
