    There was a bug in the escape analysis that would cause
    the slice implicitly created to hold varargs parameters to always
    escape, as well as the appended to slice argument.  The intended
    behavior was that the elements of the appendee and appended to
    slice would escape to the heap.  Alongside of these issues,
    the varargs slice would also have a chance to be initialized to an
    invalid memory location if it were stack-allocated.  This has been
    fixed as well.

From-SVN: r240796

The test assumes ints are atleast 32 bits wide. For the avr
target, ints are 16 bits wide. This leads VRP to conclude
that a right shift by 9 followed by an equality comparison 
to 0x74 can never be true. VRP eliminates the conditional, and
the code ends up unconditionally calling __builtin_abort.

Fixed the testcase to use __INT32_TYPE__ for targets with less
than 32 bit wide integers, wherever the size happens to be
significant.
