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...

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/s390: Remove unused tcg_out_addi()
Remove the unused function tcg_out_addi() from the s390 TCG backend;this brings it into line with other backends.

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...
Delegate setup of TCG temporaries to targets
Delegate TCG temp_buf setup to targets, so that they can use a stackframe later instead.

cpu-exec.c: avoid AREG0 use
Make functions take a parameter for CPUState instead of relyingon global env. Pass CPUState pointer to TCG prologue, which movesit to AREG0.
Thanks to Peter Maydell and Laurent Desnogues for the ARM prologuechange.
Revert the hacks to avoid AREG0 use on Sparc hosts....

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: Make some tcg-target.c routines static.
Both tcg_target_init and tcg_target_qemu_prologueare unused outside of tcg.c.
tcg: Add TYPE parameter to tcg_out_mov.
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64to perform the move at the proper width, which may elide a REX prefix.
Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data"...
tcg: Allow target-specific implementation of NOR.
tcg: Allow target-specific implementation of NAND.
tcg: Allow target-specific implementation of EQV.
tcg: Name the opcode enumeration.
Give the enumeration formed from tcg-opc.h a name: TCGOpcode.Use that enumeration type instead of "int" whereever appropriate.
remove remaining occurrences AREG[1-9] and TCG_AREG[1-9]
