[3.7] bpo-9566: Fix compiler warnings on Windows (GH-12920)

* bpo-9566: Fix compiler warnings in gcmodule.c (GH-11010)

Change PyDTrace_GC_DONE() argument type from int to Py_ssize_t.

(cherry picked from commit edad38e3e05586ba58291f47756eb3fb808f5577)

* bpo-30465: Fix C downcast warning on Windows in ast.c (#6593)

ast.c: fstring_fix_node_location() downcasts a pointer difference to
a C int. Replace int with Py_ssize_t to fix the compiler warning.

(cherry picked from commit fb7e7992beec7f76cc2db77ab6ce1e86446bfccf)

* bpo-9566: Fix compiler warnings in peephole.c (GH-10652)

(cherry picked from commit 028f0ef4f3111d2b3fc5b971642e337ba7990873)

* bpo-27645, sqlite: Fix integer overflow on sleep (#6594)

Use the _PyTime_t type and round away from zero (ROUND_UP,
_PyTime_ROUND_TIMEOUT) the sleep duration, when converting a Python
object to seconds and then to milliseconds. Raise an OverflowError in
case of overflow.

Previously the (int)double conversion rounded towards zero
(ROUND_DOWN).

(cherry picked from commit ca405017d5e776a2e3d9291236e62d2e09489dd2)
