aae2456ac0 tcg: Merge INDEX_op_{ld,st}_{i32,i64,i128} 
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.

e2f5ee36af tcg/optimize: With two const operands, prefer 0 in arg1 
For most binary operands, two const operands fold.
However, the add/sub carry opcodes have a third input.
Prefer "reg, zero, const" since many risc hosts have a
zero register that can fit a "reg, reg, const" insn format.

aeb3514bd0 tcg/optimize: Handle add/sub with carry opcodes 
Propagate known carry when possible, and simplify the opcodes
to not require carry-in when known.  The result will be cleaned
up further by the subsequent liveness analysis pass.

76f4278029 tcg: Add add/sub with carry opcodes and infrastructure 
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.
