tcg/optimize: rework copy progagation

The copy propagation pass tries to keep track what is a copy of what
and what has copy of what, and in addition it keep a circular list of
of all the copies. Unfortunately this doesn't fully work: a mov from
a temp which has a state "COPY" changed it into a state "HAS_COPY"....

tcg/optimize: do copy propagation for all operations

It is possible to due copy propagation for all operations, even the one
that have side effects or clobber arguments (it only concerns input
arguments). That said, the call operation should be handled differently...

tcg/optimize: optimize "op r, a, a => mov r, a"

Now that we can easily detect all copies, we can optimize the
"op r, a, a => mov r, a" case a bit more.

tcg/optimize: optimize "op r, a, a => movi r, 0"

Now that it's possible to detect copies, we can optimize the case
the "op r, a, a => movi r, 0". This helps in the computation of
overflow flags when one of the two args is 0.

tcg/optimize: further optimize brcond/movcond/setcond

When both argument of brcond/movcond/setcond are the same or when one
of the two values is a constant equal to zero, it's possible to do
further optimizations.

tcg/optimize: prefer the "op a, a, b" form for commutative ops

The "op a, a, b" form is better handled on non-RISC host than the "op
a, b, a" form, so swap the arguments to this form when possible, and
when b is not a constant.

This reduces the number of generated instructions by a tiny bit....

tcg: remove #ifdef #endif around TCGOpcode tests

Commit 25c4d9cc changed all TCGOpcode enums to be available, so we don't
need to #ifdef #endif the one that are available only on some targets.
This makes the code easier to read.

tcg/optimize: check types in copy propagation

The copy propagation doesn't check the types of the temps during copy
propagation. However TCG is using the mov_i32 for the i64 to i32
conversion and thus the two are not equivalent.

With this patch tcg_opt_gen_mov() doesn't consider two temps of...
