[Bug target/28516] New: [4.2 regression] arm_unwind_emit_set, at config/arm/arm.c:15419 with -fexceptions

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Robert Schwebel reported on libc-ports that glibc failed to build on softfloat
arm eabi with an ICE, see
http://sources.redhat.com/ml/libc-ports/2006-07/msg00027.html

It fails with -fexceptions and works without.  I've attached a reduce testcase.
I assume this is a regression but I don't have an older cross compiler so I
cannot say for sure.
