target-i386: Decode the VEX prefixes

No actual required uses of these encodings yet.

target-i386: Tidy prefix parsing

Avoid duplicating switch statement between 32 and 64-bit modes.

target-i386: Use CC_SRC2 for ADC and SBB

Add another slot in ENV and store two of the three inputs. This lets us
do less work when carry-out is not needed, and avoids the unpredictable
CC_OP after translating these insns.

target-i386: Make helper_cc_compute_{all,c} const

Pass the data in explicitly, rather than indirectly via env.
This avoids all sorts of unnecessary register spillage.

target-i386: Don't reference ENV through most of cc helpers

In preparation for making this a const helper.

By using the proper types in the parameters to the helper functions,
we get to avoid quite a lot of subsequent casting.

target-i386: use gen_op for cmps/scas

Replace low-level ops with a higher-level "cmp %al, (A0)" in the case
of scas, and "cmp T0, (A0)" in the case of cmps.

target-i386: introduce gen_jcc1_noeob

A jump that ends a basic block or otherwise falls back to CC_OP_DYNAMIC
will always have to call gen_op_set_cc_op. However, not all jumps end
a basic block, so introduce a variant that does not do this.

This was partially undone earlier (i386: drop cc_op argument of gen_jcc1),...

target-i386: Update cc_op before TCG branches

Placing the CC_OP_DYNAMIC at the join is less effective than
before the branch, as the branch will have forced global registers
to their home locations. This way we have a chance to discard
CC_SRC2 before it gets stored....

target-i386: optimize flags checking after sub using CC_SRCT

After a comparison or subtraction, the original value of the LHS will
currently be reconstructed using an addition. However, in most cases
it is already available: store it in a temp-local variable and save 1...

target-i386: kill cpu_T3

It is almost unused, and it is simpler to pass a TCG value directly
to gen_shiftd_rm_T1_T3. This value is then written to t2 without
going through a temporary register.
