Kees Cook f6a291e73a UPSTREAM: lib: Introduce test_stackinit module 
Upstream commit 50ceaa95ea09 ("lib: Introduce test_stackinit module").

Adds test for stack initialization coverage. We have several build options
that control the level of stack variable initialization. This test lets us
visualize which options cover which cases, and provide tests for some of
the pathological padding conditions the compiler will sometimes fail to
initialize.

All options pass the explicit initialization cases and the partial
initializers (even with padding):

test_stackinit: u8_zero ok
test_stackinit: u16_zero ok
test_stackinit: u32_zero ok
test_stackinit: u64_zero ok
test_stackinit: char_array_zero ok
test_stackinit: small_hole_zero ok
test_stackinit: big_hole_zero ok
test_stackinit: trailing_hole_zero ok
test_stackinit: packed_zero ok
test_stackinit: small_hole_dynamic_partial ok
test_stackinit: big_hole_dynamic_partial ok
test_stackinit: trailing_hole_dynamic_partial ok
test_stackinit: packed_dynamic_partial ok
test_stackinit: small_hole_static_partial ok
test_stackinit: big_hole_static_partial ok
test_stackinit: trailing_hole_static_partial ok
test_stackinit: packed_static_partial ok
test_stackinit: packed_static_all ok
test_stackinit: packed_dynamic_all ok
test_stackinit: packed_runtime_all ok

The results of the other tests (which contain no explicit initialization),
change based on the build's configured compiler instrumentation.

No options:

test_stackinit: small_hole_static_all FAIL (uninit bytes: 3)
test_stackinit: big_hole_static_all FAIL (uninit bytes: 61)

CONFIG_GCC_PLUGIN_STRUCTLEAK_USER=y
This only tries to initialize structs with __user markings, so
only the difference from above is now the "user" test passes:

remain uninitialized):

CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL=y
