Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t). However since the introduction of
the iotlb field it has only been used for RAM accesses.
This means we can change the type of addend to unsigned long, and remove

Make cpu_get_real_ticks use mfspr
PowerPC CPUs have had two ways to read the time base for quite some time now.
They provide it using the mfspr instruction or - if a special bit is set in
that opcode - using mftb. For timekeeping we're currently using mftb.
While trying to get Qemu up and running on an e500v2 system, I stumbled over
the CPU not supporting mftbu. It just throws an illegal instruction trap.
So let's read the SPR values instead. All PPC CPUs should support them anyways.
I tested this patch on an e500v2 system where it makes qemu work and on my 970MP
system with 32-bit user space where everything still works with this patch

tcg: initial ia64 support
A few words about design choices:
* On IA64, instructions should be grouped by bundle, and dependencies
between instructions declared. A first version of this code tried to
schedule instructions automatically, but was very complex and too
invasive for the current common TCG code (ops not ending at
instruction boundaries, code retranslation breaking already generated
code, etc.) It was also not very efficient, as dependencies between
TCG ops is not available.
Instead the option taken by the current implementation does not try
to fill the bundle by scheduling instructions, but by providing ops
not available as an ia64 instruction, and by offering 22-bit constant
loading for most of the instructions. With both options the bundle are
filled at approximately the same level.
* Up to 128 registers can be affected to a function on IA64, but TCG
limits this number to 64, which is actually more than enough. The
register affectation is the following:
- r0: used to map a constant argument with value 0
- r1: global pointer
- r2, r3: internal use
- r4 to r6: not used to avoid saving them
- r7: env structure
- r8 to r11: free for TCG (call clobbered)
- r12: stack pointer
- r13: thread pointer
- r14 to r31: free for TCG (call clobbered)
- r32: reserved (return address)
- r33: reserved (PFS)
- r33 to r63: free for TCG
* The IA64 architecture has only 64-bit registers and no 32-bit
instructions (the only exception being cmp4). Therefore 64-bit
registers and instructions are used for 32-bit ops. The adopted
strategy is the same as the ABI, that is the higher 32 bits are
undefined. Most ops (and, or, add, shl, etc.) can directly use
the 64-bit registers, while some others have to sign-extend (sar,
div, etc.) or zero-extend (shr, divu, etc.) the register first.

linux-user/ia64: workaround ia64 strangenesses
ia64 has some strangenesses that need to be workaround:
- it has a __clone2() syscall instead of the using clone() one, with
different arguments, and which is not declared in the usual headers.
- ucontext.uc_sigmask is declared with type long int, while it is
actually of type sigset_t.
- uc_mcontext, uc_sigmask, uc_stack, uc_link are declared using #define,
which clashes with the target_ucontext fields. Change their names to
tuc_*, as already done for some target architectures.
