compiler: stack allocate storage for temp slices.

    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

escape: Avoid allocation of varargs parameter.

    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

Fix pr69941.c test failure for avr

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.

DWARF: move pessimistic DWARF version checks for imported entities

A check in dwarf2out_imported_module_or_decl prevents
DW_TAG_imported_module from being emitted as it was introduced in the
DWARFv3 standard. However, this also prevents valid strict DWARFv2
constructs such as DW_TAG_imported_declaration from being emitted in
dwarf2out_imported_module_or_decl_1.

The latter already protects the emission of newer DWARF tags with
appropriate checks, so the one in the former is redundant and
pessimistic.  This function is already called from places like
process_scope_var, which are not protected anyway.

This patch moves the check in dwarf2out_imported_module_or_decl so that
in strict DWARFv2 mode, tags like DW_TAG_imported_declaration are
emitted while DW_TAG_imported_module are not.
