Work around QEMU bug #1668041 differently, by which floating-point
division by zero is not correctly trapped for i386 and amd64:

https://bugs.launchpad.net/qemu/+bug/1668041

Make trigger_fpe() cause integer division by zero for x86, and
floating-point one for other architectures. Also, assertions for
si_code in *_crash_fpe tests are commented out for now. They
should be cleaned up after the bug is fixed.

Now, *_crash_fpe tests are working also on powerpc.

Suggested by kamil.

Turn trigger_fpe() back to integer division by zero for a while
until QEMU bug #1668041 is fixed:

https://bugs.launchpad.net/qemu/+bug/1668041

by which floating-point division by zero is not trapped correctly
both on amd64 and i386.

Skip *_crash_fpe tests on powerpc, where integer division by zero
is never trapped.

Let trigger_fpe() cause floating-point divide by zero exception, instead of
integer one, which is not trapped for powerpc and aarch64.

Note that it is checked in lib/libc/gen/t_siginfo whether integer divide by
zero is interpreted as SIGFPE or not.

Now, all *_crash_fpe tests pass for powerpc, and nothing changes for amd64
at least.

Move signal tests out of t_ptrace_wait.c to t_ptrace_signal_wait.h

The same tests are now included with the preprocessor in t_ptrace_wait.c.

No functional change intended.
