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.

This fixes a few things after Paul's improvements for TCG debugging:
- change TCGv_i64 field name to something different from
TCGv_i32
- fix things in tcg that the above change made visible.

According to malc TCG will often genereate an add2/sub2/mul2 with low
half of the output in the same register as high half of one of the
inputs, so account for that.

Otherwise when tb_exit generates a jump beyond the pc-relative range,
tcg_out_goto() spans two/three instructions and we load the tb return
value from a wrong address. This is #ifdefed out currently because
we take care for the jumps to be local.
Problem spotted by Steffen Liebergeld.

Calling the clear cache syscall directly generates an illegal instruction
on some (armv4) kernels.

LD/STD/LWA require displacement to be multiple of 4, provide
tcg_out_ldsta which checks the supplied displacement and falls
back on indexed variant when the check fails. All uses of
LD/STD/LWA outside of tcg_out_ldst appear to be safe.

Use the same order as the _i32 version (pure code move). Suggested by
Laurent Laurent Desnogues.

Add a subfi (subtract from immediate) wrapper, useful for the PPC target.

Move addi_i64, muli_i64 and subi_i64 out of #if TCG_TARGET_REG_BITS
as both implementations are strictly identical. Use the same
optimisation (ie when imm == 0) for addi_i64 and subi_64 than the
32-bit version.

Use rldimi instead of rldicr/or pair, saves us one instruction.

Avoids nasty warnings about flush_icache_range from gcc4 and inability
to compile [cpu-]exec.c with gcc3 and -O, also the function is much
too large to be candidate for inlining anyway.
