tcg: get rid of DEF2 in tcg-opc.h

tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.

Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand). For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with...

tcg: fix assertion with --enable-debug

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.

tcg: add ext{8,16,32}u_i{32,64} TCG ops

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....

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...
