[Bug objc++/44518] New: [4.5/4.6 regression] objc++ encode-2.mm and encode-3.mm fail on several platforms

[mikpe at it dot uu dot se]

On 4_5-branch, the objc++ encode-2.mm and encode-3.mm tests started to fail
recently on several platforms:

FAIL: obj-c++.dg/encode-2.mm scan-assembler
{?={Vec<double>=ddi}{Vec<float>=ffi}fd{Vec<char>=cci}i}
FAIL: obj-c++.dg/encode-3.mm -fgnu-runtime execution test

Compare e.g.

http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg00958.html (s390x, r160516)
http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg00567.html (arm, r160235)
http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg00364.html (powerpc64,
r160235)

with

http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg01078.html (s390x, r160582)
http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg01249.html (arm, r160582)
http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg01118.html (powerpc64,
r160582)

I suspect the PR32052 backport in r160541.

Testsuite results before and after the corresponding trunk commit (r158958)
show a similar regression.  Compare e.g.
