This is a bunch of fixes/changes for the s390 architecture. It also
contains the fixes from the previous pull request, which did not make
it yet.
Overall it contains
- a fix for kexec without kdump (which uses diag308 subcode 0 instead of 1)
- several sclp related fixes
- some initial sclp migration code
- the sclp line mode console
- A fix for a boot problem with the virtio ccw ipl bios
- zeroed out padding bytes for the notes section of dump-guest-memory
- some cleanups

Less conditional compilation.  Merge an add insn with the indexed
memory load insn.  Load the tlb addend earlier.  Avoid the address
update memory form.

Fix a bug in not allowing large enough tlb offsets for some guests.

Previously we'd only handle 16-bit offsets from memory operand without falling
back to indexed, but it's easy to use ADDIS to handle full 32-bit offsets.

This also lets us unify code that existed inline in tcg_out_op for handling
addition of large constants.

The new R2 temporary was marked reserved for the AIX calling convention, but
the register really is call-clobbered and since tcg generated code has no use
for a TOC, it's available for use.
Signed-off-by: NRichard Henderson <rth@twiddle.net>

Remove conditionalization from tcg_target_reg_alloc_order, relying on
reserved_regs to prevent register allocation that shouldn't happen.
So R11 is now present in reg_alloc_order for __APPLE__, but also now
reserved.

Sort reg_alloc_order into call-saved, call-clobbered, and parameters.
This reduces the effect of values getting spilled and reloaded before
function calls.

Whether or not it is reserved, R2 (TOC) is always call-clobbered.

Instead of bare N, for clarity.  The only (intentional) exception made

The fix is that sparc has so many mmu modes that the last one overflowed
the 16-bit signed offset we assumed would fit.  Handle this, and check
the new assumption at compile time.

Load the tlb addend earlier for the fast path.

Remove the explicit address + addend and make use of index addressing.

Adjust constraints for qemu_ld64 such that we don't clobber the address
register or tlb addend before loading both values.

These use a 32-bit load-of-immediate to save a mflr+addi+mtlr sequence.
Tested with a Windows 98 guest (pretty much the most recent thing I
could run on my PPC machine) and kvm-unit-tests's sieve.flat.  The
speed up for sieve.flat is as high as 10% for qemu-system-i386, 25%

kernel code.

With this patch I am able to execute m68k binaries
