This patch removes useless type information in some calls to
tcg_temp_local_new. It also removes the parameter from the
macro declaration; if a target has to use a specific non-default
size then it should use tcg_temp_local_new_{i32,i64}.

Since most IO devices are integrated into the 440EP chip, "Bamboo support"
mostly entails implementing the -kernel, -initrd, and -append options.
These options are implemented by loading the guest as if u-boot had done it,
i.e. loading a flat device tree, updating it to hold initrd addresses, ram
size, and command line, and passing the FDT address in r3.
Since we use it with KVM, we enable the virtio block driver and include hooks
necessary for KVM support.

Rework the memory load/store:
- Unify load/store functions for 32-bit and 64-bit CPU
- Don't swap values twice for bit-reverse load/store functions
in little endian mode.
- On a 64-bit CPU in 32-bit mode, do the address truncation for
address computation instead of every load store. Truncate the
address when incrementing the address (if needed)
- Cache writes to access_types.
- Add a few missing calls to gen_set_access_type()

This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.
First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.
Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

This patch refactors the way the CPU state is handled that is associated

watchpoint fixes (patch "Restore pc on watchpoint hits").

There was a bogus case where two system debug ops get generated. This
patch removes the broken system debug op. This was a left over after
making some changes to correctly generate debug ops on branch
operations inside gen_goto_tb();
The test case against this patch is to turn on single stepping with
timers, boot a linux kernel, set a breakpoint a do_fork and in gdb
execute "si 3000". Then qemu-system-ppc will fault executing a debug
op, which should not have been executed.
