Richard Smith 4a7aefefaa Add support for operators on Core.IntLiteral. (#4716)
Fixes integer builtins to produce the correct values (and not
CHECK-fail) when used on integer literals. Also adds impls to the
prelude to use the new builtins to perform operations on integer
literals.

Perhaps most importantly, this allows directly initializing `i32` values
with negative numbers, as the negation operation on integer literals now
works.

For testing I've added tests for use of literals with one operator in
each class (addition, multiplication, ordering, bitwise, etc) for which
there are distinct rules or overflow behavior, rather than exhaustively
testing all the combinations. This is aimed at finding a good tradeoff
between maintainability of the tests and thorough test coverage.

Also fixes lowering of heterogeneous shifts and comparisons. These are
currently disabled when one of the operands is an integer literal, but
we may want to allow that when the integer literal operand has a known
constant value.
