tcg-s390: Use qemu_getauxval in query_facilities
No need to set up a SIGILL signal handler for detection anymore.
Remove a ton of sanity checks that must be true, given that we'rerequiring a 64-bit build (the note about 31-bit KVM is satisfiedby configuring with TCI)....
tcg: Add qemu_ld_st_i32/64
Step two in the transition, adding the new ldst opcodes. Keep the oldopcodes around until all backends support the new opcodes.

tcg: Add tcg-be-null.h
This is a no-op backend data implementation, for those targets thatare not currently using the load/store optimization path.
This is prepatory to always requiring these functions in all backends.

exec: Split softmmu_defs.h

tcg-s390: Fix merge error in tgen_brcond
When the TCG condition codes were re-organized last year,we failed to update all of the "old-style" tests for unsigned.
tcg-s390: Remove constraint letters for and
Since we have a free temporary and can always just load the constant, weought to do so, rather than spending the same effort constraining the const.
tcg-s390: Use risbgz for andi
This is immediately usable by the tlb lookup code.
tcg-s390: Cleanup argument shuffling fixme in softmmu code
tcg-s390: Use load-address for addition
Since we're always in 64-bit mode, load address performs a full64-bit add. Use that for 3-address addition, as well as forlarger constant addends when we lack extended-immediates facility.
tcg-s390: Use all 20 bits of the offset in tcg_out_mem
This can save one insn, if the constant has any bits in 32-63 set,but no bits in 21-31 set. It never results in more insns.
tcg-s390: Properly allocate a stack frame.
Set TCG_TARGET_CALL_STACK_OFFSET properly for the abi. Allocate thestandard TCG_STATIC_CALL_ARGS_SIZE. And while we're at it, allocatespace for CPU_TEMP_BUF_NLONGS.
tcg-s390: Remove useless preprocessor conditions
We only support 64-bit code generation for s390x.Don't clutter the code with ifdefs that suggest otherwise.
