1b530a6dfc Add new command line option -singlestep for tcg single stepping.
This replaces a compile time option for some targets and adds
this feature to targets which did not have a compile time option.

Add monitor command to enable or disable single step mode.

Modify monitor command "info status" to display single step mode.

4f396364a6 Remove GenOpFunc typedefs
This patch removes the GenOpFunc typedefs from exec-all.h, which are no
longer needed, now that dyngen has been removed.

7d99a001df Add noreturn function attribute
Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.

[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h.
I've been told that these conflicts will get resolved in the future
(/me will try to have a look as well - as time permits). ]

e58ffeb322 Remove all traces of __powerpc__
According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the
ubiquitous define which should be used to test whether gcc targets
PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.

49516bc0d6 Some cleanups after dyngen removal
this patch removes some now unused things after dyngen removal.

1. dyngen-exec.h:  op_param, op _jmp and some associated macros
   are now unused;
2. Makefile.target:  tcg-dyngen is not needed anymore
2. tcg/tcg-op.h, tcg/tcg-opc.h:  gen-op.h is dead
3. tcg.c:
    - INDEX_op_end is now the first op
    - CONFIG_DYNGEN_OP is never defined
4. tcg.h:  dyngen_op not needed anymore
5. exec-all.h:  remove some ASM macros.

  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
