On 32-bit hosts op_qemu_ld32s is unused. Remove it to fix the
following assertion failure:
qemu-alpha: tcg/tcg.c:1055:
tcg_add_target_add_op_defs: Assertion `tcg_op_defs[op].used' failed.

Previously ORC was always implemented by tcg-op.h with
an explicit NOT opcode. Allow a target implementation.

Currently zero extensions ops are implemented by a and op with a
constant. This is then catched in some backend, and replaced by
a zero extension instruction. While this works well on RISC
machines, this adds a useless register move on non-RISC machines.
Example on x86:
ext16u_i32 r1, r2
is translated into
mov %eax,%ebx
movzwl %bx, %ebx
while the optimized version should be:
movzwl %ax, %ebx
This patch adds ext{8,16,32}u_i{32,64} TCG ops that can be
implemented in the backends to avoid emitting useless register
moves.

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.
