14be64018f Modify the two address instruction pass to remove the duplicate
operand of the instruction and thus simplify the register allocation.

f0339396c1 IMULri* instructions do not require their first two registers operands
to be the same (IOW they are not two address instructions).

cf93cdde56 Add (currently disabled) support to the instruction selector to only insert
FP_REG_KILL instructions at the end of blocks involved with critical edges.

Fix a bug where FP_REG_KILL instructions weren't inserted in fall through
unconditional branches.  Perhaps this will fix some linscan problems?

07ad64231f Eliminate the isStringCompatible function, using ConstantArray::isString.
It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away.  This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.

Also slightly restructure some code to be cleaner.

e0bb3e766d Remove floating point killer pass. This is now implemented in the
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.
