Some cleanups after dyngen removal

Browse source 
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.
