Reduce ifdefs, share more code between paths, reduce the number of TCG
ops generated. Avoid re-computing the size of the operation across
gen_pop_T0 and gen_pop_update.
Add forgotten zero-extension in the TARGET_X86_64, !CODE64, ss32 case.

Changing the domain to TCGMemOp makes it easier to interoperate
with other portions of the rest of the translator.
We now only have one domain for size operands inside the translator,
which makes things less confusing all the way around. There are
still a number of helpers that continue to use the log2-1 domain.

These functions used the aflags/dflags domain, which is log2-1
of the byte size. Confusingly, they used enumeration values
from the log2 domain.
Change the domain of the parameter and update all callers.
Since we're now in a common domain, defer the deposit/extend/mov
decision to gen_op_mov_reg_v.

The 'ot' variables (operand type?) hold the log2(byte size) of
the operand being manipulated. This is the same as the MO_SIZE
subset of the TCGMemOp. Indeed, we often pass 'ot' to the
tcg_gen_qemu_ld/st functions.
Changing the type from 'int' makes it easier to see what domain
the variable should be.
This does require adding some default cases to some switch statements,
to avoid the 'unhandled enumeration value' warning that would result
from the change of type.

the zero-extension has already happened via the previous load.

For the known MO_32/MO_64 cases, we don't need to extend a 32-bit temp
into a 64-bit temp before storing into the hardware register.
We do need the extension for the MO_8/MO_16 cases, in order for the
deposit_tl operation to work, so leave those alone.

Always perform a sign-extending load. In the extremely unlikely
case that we've used an 0x66 prefix, the extension to 64-bits is
unnecessary but not wrong; the store will still examine only 16 bits.
