Implement all the integer comparison operators in swift.swift.  Despite
the indirection, each of these compiles into nice simple IR at -O3, with:
 swift swift.swift -I test -emit-llvm | opt -O3 -S | less

for example:

define i1 @_TSsop1gFT3lhsNSs5int643rhsS__NSs4bool(i64, i64) nounwind readnone {
entry:
  %2 = icmp sgt i64 %0, %1
  ret i1 %2
}
