* tests/list_atomic.template (XSIZE_list_atomicXX): Use "static"
modifier for "val" local variable to initialize it (cannot use direct
assignment to zero because "val" type could be a SIMD vector type if
XCTYPE is AO_double_t) to workaround GCC v4.4.3
"'val' is used uninitialized in this function" warning reported for
AO_load.

* tests/Makefile.am (list_atomic.c): Iterate over XSIZE/XCTYPE (in
addition to XX); expand XX also as _dd_acquire_read.
* tests/list_atomic.template (XSIZE_list_atomicXX): Define 'val' local
variable only if used (needed for AO_double_t case).

* tests/list_atomic.template (list_atomicXX): Add AO_XSIZE_andXX,
AO_XSIZE_orXX, AO_XSIZE_xorXX invocations.

* tests/Makefile.am (list_atomic.c): Substitute XSIZE/XCTYPE for AO_t.
* tests/list_atomic.template (list_atomicXX): Parameterize with XSIZE
and XCTYPE (except for AO_nop and AO_test_and_set).

* tests/Makefile.am (BUILT_SOURCES, CLEANFILES): Add "list_atomic.o".
* tests/Makefile.am (list_atomic.o): New rule (to verify list_atomic.c
is valid C code).
* tests/list_atomic.template (list_atomicXX): Use "volatile" for "val"
local variable.
* tests/list_atomic.template (list_atomicXX): Define "oldval", "newval",
"ts" and "incr" local variables only if used; cast string literals to
void (to prevent compiler warnings).
* tests/list_atomic.template (list_atomicXX): Use AO_t type for "incr"
local variable instead of C long type.
* tests/list_atomic.template (list_atomicXX): Define "oldval",
"newval", "incr" as statitc local variables, and remove explicit
initialization to zero (to void problems with initialization of these
variables for AO_double_t case if the latter is a struct).

* tests/list_atomic.template (list_atomicXX): Use AO_t instead of
deprecated AO_T.
* tests/list_atomic.template (list_atomicXX): Use AO_TS_t instead of
deprecated AO_TS_T.
* tests/test_atomic.c (lock): Likewise.
