tcg: Remove TCG_TARGET_HAS_GUEST_BASE define
GUEST_BASE support is now supported by all TCG backends, and isnow mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASEdefine (set by every backend) and the error if it is unset.

tcg: Add TCG_COND_NEVER, TCG_COND_ALWAYS
There are several cases that can be handled easier inside bothtranslators and code generators if we have out-of-band valuesfor conditions. It's easy enough to handle ALWAYS and NEVER inthe natural way inside the tcg middle-end....
tcg: Add is_unsigned_cond
Before we rearrange the TCG_COND enumeration, add a predicate forthe (single) use of comparisons vs TCGCond.

tcg: remove obsolete jmp op
The TCG jmp operation doesn't really make sense in the QEMU context, itis unused, it is not implemented by some targets, and it is wronglyimplemented by some others.
This patch simply removes it.

tcg: Remove tcg_target_get_call_iarg_regs_count
The TCG targets no longer need individual implementations.
Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9,'flags' is no longer used in tcg_target_get_call_iarg_regs_count.
The remaining tcg_target_get_call_iarg_regs_count is trivial and only...
tcg: Introduce movcond
Implemented with setcond if the target does not providethe optional opcode.
Remove unused CONFIG_TCG_PASS_AREG0 and dead code
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.
Remove dyngen-exec.h and all references to it. Although included byhw/spapr_hcall.c, it does not seem to use it....
tcg/s390: fix ld/st with CONFIG_TCG_PASS_AREG0
The load/store slow path has been broken in e141ab52d:- We need to move 4 registers for store functions and 3 registers for load functions and not the reverse.- According to the s390x calling convention the arguments of a function...
softmmu templates: optionally pass CPUState to memory access functions
Optionally, make memory access helpers take a parameter for CPUStateinstead of relying on global env.
On most targets, perform simple moves to reorder registers. On i386,switch from regparm(3) calling convention to standard stack-based...
