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.

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.

rename the opcode to maintain uniformity.

Begin to rely on TCGOp.type to discriminate operations,
rather than two different opcodes. Convert mov first.
Introduce TCG_OPF_INT in order to keep opcode dumps the same.
