e28aaa1d45 Make async-style syscalls work on ppc64, by using rt_sigprocmask 
instead of sigprocmask.

In the process, discover that error handling for
ML_(do_syscall_for_client_WRK) on all platforms has always been
broken, in the sense that the sigprocmasks (which are important) could
silently fail.  This commit fixes that up too (only on ppc64-linux at
the moment, so all other platforms are probably broken now).

4d4bc5d1f6 fixed up ppc64 assembly with .opd sections 
do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.

always use dot_prefix for label calls

not wrapping assembly with
.section ".text"
...
.previous
 - ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?

b714685c63 Take ppc64 startup further along the road 
- fixed launcher.c to recognise ppc32/64-linux platforms properly
 - lots of assembly fixes to handle func descriptors, toc references, 64bit regs.
 - fixed var types in vki-ppc64-linux

Now gets as far as VG_(translate), but dies from a case of invalid orig_addr.

418aae5c97 Hmm. Perhaps all those top-level pieces of assembly weren't such a 
clever idea.  There's no reason to assume the assembler is in
.text-mode when it encounters them, and as gcc 2.96 rudely
demonstrates, sometimes it isn't.  So put .text in front of all of
them.

7039eaa9ac sys_tgkill: hand the syscall to the kernel in the standard way, rather 
than doing it inline.  Doing it inline screws up on ppc32-linux if
we're sending an async signal to ourselves (the same thread) because
the kernel immediately hands the signal to async_sighandler() which
then dies at the assertion that this thread's state is VgTs_WaitSys.
From which I conclude this wrapper has always had a race against the
kernel which did not show up on x86 or amd64.  (and/or that I don't
understand this stuff too well)

91b44ff30e Use VG_(ntohl) and VG_(ntohs) to decode IP addresses and ports. Note 
that this also required reversing the order of the arguments to the
print call as the previous ordering assumed that the address was still
byte swapped.

4e648a2346 Fix up ppc32-linux handlers for sys_sigreturn and sys_rt_sigreturn. I really 
have no idea how these work (what's there is a conceptual transcription of
what we have for x86-linux) and so if those of you more Skilled In The Art 
Of Signals than myself would care to peer at it, that would be appreciated.
