Generate type check predicates for secondary type variables.

Browse Source 
The encoding tables are keyed by the controlling type variable only. We
need to distinguish different encodings for instructions with multiple
type variables.

Add a TypePredicate instruction predicate which can check the type of an
instruction value operand. Combine type checks into the instruction
predicate for instructions with more than one type variable.

Add Intel encodings for fcvt_from_sint.f32.i64 which can now be
distinguished from fcvt_from_sint.f32.i32.
