During the lowering phase, the variable arguments to a varargs call are
packaged up into a temporary slice object; the storage for this slice
was being unconditionally allocated on the heap. Heap allocation is not
necessary, however, if the varargs call correspond to an "append", since
the append runtime routine only reads the slice storage (as opposed to
stashing away the storage pointer). Enhance the lowering code to keep
the slice storage on the stack for append() calls, to improve
performance.
Addresses issue golang/go#17304.

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.

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.
