arm_boot: Change initrd load address to "halfway through RAM"
To avoid continually having to bump the initrd load address
to account for larger kernel images, put the initrd halfway
through RAM. This allows large kernels on new boards with lots
of RAM to work OK, without breaking existing usecases for
boards with only 32MB of RAM.
Note that this change fixes in passing a bug where we were
passing an overly large max_size to load_image_targphys()
for the initrd, which meant that we wouldn't correctly refuse
to load an enormous initrd that didn't actually fit into RAM.

target-ppc: Extend FPU state for newer POWER CPUs
This patch adds some extra FPU state to CPUPPCState. Specifically,
fpscr is extended to a target_ulong bits, since some recent (64 bit)
CPUs now have more status bits than fit inside 32 bits. Also, we add
the 32 VSR registers present on CPUs with VSX (these extend the
standard FP regs, which together with the Altivec/VMX registers form a
64 x 128bit register file for VSX).
We don't actually support the instructions using these extra registers
in TCG yet, but we still need a place to store the state so we can
sync it with KVM and savevm/loadvm it. This patch updates the savevm
code to not fail on the extended state, but also does not actually
save it - that's a project for another patch.

configure: use -Wwombat to test whether gcc recognizes -Wno-wombat
gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.
