The ppc32 backend isn't getting much love and attention recently, with
all of the improvements coming from me into the ppc64 backend. Let's
reduce the maint burden a bit and combine them.
This does have a few other patches that are not strictly related to the
merge of the backends, such as addition of ELFv2 support, but I think
those come naturally at the point we're merging the two other ABIs from
the 32-bit port.
I've tested this as thouroghly as I can on a Power7 host, both ppc64 and
ppc32 editions. Though of course even with the 32-bit abi a power7 host
will execute 64-bit instructions. Which means if anyone has access to a
proper 32-bit ppc system, I'd be grateful if you could verify I haven't
missed any necessary conditionalization. Tom Musta gave me a Tested-by
for v2 on an ELFv2 system; it might be worth re-doing that just in case.

Changes v1-v2:
* mulsh_i32 typo fixed (Uli)
* ppc32 qemu_st_i64 bug fixed
* ppc64 boot problem Tom reported by a generic tcg optimization fix
Changes v2-v3:
* Rebased,
* Dropped patch 26, Streamline USE_DIRECT_JUMP. This seems to have
some timing/flushing issues on 32-bit which I don't have time to
understand at the moment.
