Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

The lswx instruction checks whether the desired string actually fits
into all defined registers. Unfortunately it does the calculation wrong,
resulting in illegal instruction traps for loads that really should fit.
Fix it up, making Mac OS happier.

Provide a degenerate implementation of the tbegin instruction. This
implementation always fails the transaction, recording the failure
per Book II Section 5.3.2 of the Power ISA V2.07.

This allows running PPC64 little-endian in user mode if target is configured
that way. In PPC64 LE user mode we set MSR.LE during initialization.

This will collect all load and store helpers soon. For now
it is just a replacement for softmmu_exec.h, which this patch
stops including directly, but we also include it where this will
be necessary in order to simplify the next patch.

Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h. This
minimizes the files that must be rebuilt when changing the macros
for file N.

The Load Vector Element (lve*x) and Store Vector Element (stve*x)
instructions not only byte-swap in Little Endian mode, they also
invert the element that is accessed. For example, the RTL for
lvehx contains this:
eb <-- EA[60:63]
if Big-Endian byte ordering then
VRT[8*eb:8*eb+15] <-- MEM(EA,2)
else
VRT[112-(8*eb):127-(8*eb)] <-- MEM(EA,2)
This patch adds the element inversion, as described in the last line
of the RTL.

The default with linux-user for dcbz on 970 is to emulate 32 byte clears.
However, redoing the dcbzl support we added a check to not honor the bit
in HID5 that sets this.
Remove the #ifdef check on linux user, so that we get 32 byte clears again.

For softmmu builds the interface from the generic code to the target
specific MMU implementation is through the tlb_fill() function. For ppc
this is currently in mem_helper.c, whereas it would make more sense in
mmu_helper.c. This patch moves it, which also allows
cpu_ppc_handle_mmu_fault() to become a local function in mmu_helper.c

The bit that makes a dcbz instruction a dcbzl instruction was declared as
reserved in ppc32 ISAs. However, hardware simply ignores the bit, making
code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4.
Thus, mark the bit as unreserved so that we properly emulate a simple dcbz
in case we're running on non-G5s.
While at it, also refactor the code to check the 970 special case during
runtime. This way we don't need to differenciate between a 970 dcbz and
any other dcbz anymore. We also allow for future improvements to add e500mc
dcbz handling.

Add an explicit CPUPPCState parameter instead of relying on AREG0
and rename op_helper.c (which only contains load and store helpers)
to mem_helper.c. Remove AREG0 swapping in
tlb_fill().
Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation
and interrupt handling, cpu_{ld,st}{l,uw}_data in loads and stores.
