883ef2499c __memcpy_chk: Fix signed cmp of unsigned values. 
I accidentally did a signed comparison of the size_t values passed in
for three of the _chk functions. Changing them to unsigned compares.

Add three new tests to verify this failure is fixed.

Null or constant dereferencing occurs if properties are not initialized.
On Android devices it shouldn't happen but can be faced if testing bionic
libc.so on Linux host.

05332f2ce7 Fix all debug directives. 
The backtrace when a fortify check failed was not correct. This change
adds all of the necessary directives to get a correct backtrace.

Fix the strcmp directives and change all labels to local labels.

Testing:
- Verify that the runtime can decode the stack for __memcpy_chk, __memset_chk,
  __strcpy_chk, __strcat_chk fortify failures.
- Verify that gdb can decode the stack properly when hitting a fortify check.
- Verify that the runtime can decode the stack for a seg fault for all of the
  _chk functions and for memcpy/memset.
- Verify that gdb can decode the stack for a seg fault for all of the _chk
  functions and for memcpy/memset.
- Verify that the runtime can decode the stack for a seg fault for strcmp.
- Verify that gdb can decode the stack for a seg fault in strcmp.

bd8e6749b7 cdefs.h: introduce __bos0 
Introduce __bos0 as a #define for __builtin_object_size((s), 0).
This macro is intended to be used for places where the standard
__bos macro isn't appropriate.

memcpy, memmove, and memset deliberately use __bos0. This is done
for two reasons:

1) I haven't yet tested to see if __bos is safe to use.
2) glibc uses __bos0 for these methods.
