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.

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....
w64: Change data type of parameters for flush_icache_range
The TCG targets i386 and tci needed a change of the functionprototype for w64.
This change is currently not needed for the other TCG targets,but it can be applied to avoid code differences.

tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.h
It is now declared for all tcg targets in tcg.h,so the tcg target specific declarations are redundant.

tcg: Always define all of the TCGOpcode enum members.
By always defining these symbols, we can eliminate a lot of ifdefs.
To allow this to be checked reliably, the semantics of theTCG_TARGET_HAS_* macros must be changed from def/undef to true/false.This allows even more ifdefs to be removed, converting them into...
tcg-s390: new TCG Target

tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.
Some hosts (amd64, ia64) have an ABI that ignores the high bitsof the 64-bit register when passing 32-bit arguments. Othersrequire the value to be properly sign-extended for the type.I.e. "int32_t" must be sign-extended and "uint32_t" must be...
tcg-s390: Icache flush is a no-op.
Before gcc 4.2, builtin_clear_cache doesn't exist, andafterward the gcc s390 backend implements it as nothing.
tcg: Allow target-specific implementation of NOR.
tcg: Allow target-specific implementation of NAND.
tcg: Allow target-specific implementation of EQV.

S/390 fake TCG implementation
Qemu won't let us run a KVM target without having host TCG support. Well, fornow we don't have any so let's implement a fake target that only stubs outeverything.
I tried to keep the patch as close to Uli's source as possible, so whenever...
