[turbofan] Use register for instruction operands when SameAsFirst is specified.
...
As the register allocator cannot reuse spill slots, SameAsFirst
constraint means that we would have to do an expensive move to a
differen spill slot if we choose to spill. Forcing the operand
to a register is cheaper.
In zlib, we get >10% speed-up for ia32, >25% for x64.

Apparently
SMMLS r, b, c, a
computes
r = ((a << 32) - b * c) >> 32
while the documentation is kinda misleading and states that it should
compute
r = a - ((b * c) >> 32)
The actual behavior is kinda useless, so we drop the instruction again.

Fix scheduler to correctly schedule nested diamonds.
...
The scheduler rewires control based on the last *control*
node that appears in the schedule of a block. This is not
sufficient to account for dependencies.
This patch adds additional dependencies to floating control
nodes. Given a floating control node A, every non-control
dependency of every node B that depends on A is introduces
as an additional dependency of A.
This allows the scheduler to correctly schedule two
diamonds A, B, if their only correct schedule is to
schedule B into the ifTrue successor in A.

Script streaming: UTF-8 handling fix.

The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.
This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.
