Use the same value for all targets.
Rename TARGET_INSN_START_WORDS and do not depend on
TARGET_INSN_START_EXTRA_WORDS.
Remove TCGContext.insn_start_words.

Merge into INDEX_op_{ld,st,ld2,st2}, where "2" indicates that two
inputs or outputs are required. This simplifies the processing of
i64/i128 depending on host word size.

Split these functions out from tcg_out_op.
Define outop_goto_ptr generically.
Call tcg_out_goto_ptr from tcg_reg_alloc_op.

Liveness needs to track carry-live state in order to
determine if the (hidden) output of the opcode is used.
Code generation needs to track carry-live state in order
to avoid clobbering cpu flags when loading constants.
So far, output routines and backends are unchanged.

Sink the sets of the def, nb_iargs, nb_oargs variables to
the default and do_not_remove labels. They're not really
needed beforehand, and it avoids preceding code from having
to keep them up-to-date. Note that def had *not* been kept
up-to-date; thankfully only def->flags had been used and
those bits were constant between opcode changes.

At the same time, make extrh_i64_i32 mandatory. This closes a hole
in which move arguments could be cast between TCGv_i32 and TCGv_i64.

Drop the cast from TCGv_i64 to TCGv_i32 in tcg_gen_extrl_i64_i32
an emit extrl_i64_i32 unconditionally. Move that special case
to tcg_gen_code when we find out if the output is live or dead.
In this way even hosts that canonicalize truncations can make
use of a store directly from the 64-bit host register.
