Fix wrong copying processing for last bytes in x86-32 wcscpy
...
Wrong copy algorithm for last bytes, not thread safety.
In some particular cases it uses the destination
memory beyond the string end for
16-byte load, puts changes into that part that is relevant
to destination string and writes whole 16-byte chunk into memory.
I have a test case where the memory beyond the string end contains
malloc/free data, that appear corrupted in case free() updates
it in between the 16-byte read and 16-byte write.

rtld, i386: Fix cfi directive in audit trampoline code
...
_dl_runtime_profile function has wrong cfi directive when
rewinding stack back for the pltexit path.
Only 8 bytes - 2 'pop edx' instructions from the pltentry-only
code should be rewinded back.
With attached patch, I'm able to rewind stack correctly
throught the rtld code from audit library callback.
