Qifan Pan 63134966fd [turbofan] Fix a bug of SignedBigInt64 in representation changer 
The expected behavior of the optimized code is deoptimizing when using a BigInt
as an index and throwing an error (from CheckedTaggedToInt64).
The representation changer tries to insert conversions for this case where

- The output node is represented in Word64 (SignedBigInt64)
- The use info is CheckedSigned64AsWord64

The representation changer first rematerializes the output node to
TaggedPointer because the type check is not BigInt. Then it falls wrongly to
the branch where the output representation is TaggedPointer, the output type is
SignedBigInt64 in GetWord64RepresentationFor.
