* 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
	gdbarch_pseudo_register_read_value if available.
	* i386-tdep.h (i386_pseudo_register_read_value): Declare.
	(i386_pseudo_register_read): Remove.
	* i386-tdep.c (i386_pseudo_register_read_into_value): Rename from
	i386_pseudo_register_read.  Change arguments.  Call
	mark_value_bytes_unavailable when needed.
	(i386_pseudo_register_read_value): New function.
	(i386_gdbarch_init): Call set_gdbarch_pseudo_register_read_value,
	not set_gdbarch_pseudo_register_read.
	* gdbarch.sh (pseudo_register_read_value): New method.
	* gdbarch.c, gdbarch.h: Rebuild.
	* findvar.c (value_from_register): Call get_frame_register_value.
gdb/testsuite
	* gdb.dwarf2/typeddwarf.c: XFAIL 'z' on x86-64.
	* gdb.dwarf2/typeddwarf.exp (xfail-gdb-test): Add arch_pattern
	argument.
