FIX PR2794. Make sure SIGN_EXTEND_INREG nodes introduced by LegalizeSetCCOperands are leglized. Patch by Richard Pennington.

Fix the case where an instruction is not properly marked as using all registers that alias its inputs.

instead.

So now: -fast-isel or -fast-isel=true enable fast-isel, and
-fast-isel=false disables it. Fast-isel is also on by default
with -fast, and off by default otherwise.

The kill flags were causing the allocator to think it could
allocate the use and its tied def in different registers.

than the type an i1 is promoted to (eg: i8).  Account
for this.  Noticed by Tilmann Scheller on CellSPU; he
will hopefully take care of fixing this in LegalizeDAG

It turns out that this is a fairly common operation,
