Issue #636 was that parsing hex literals resulted in incorrect values.
However, the numbers are still represented by JavaScript doubles, leading to various incorrect values.
Arithmetic operations are mostly correct up until rounding at 53 bits.
Bitwise operations are truncated to 32 bits.

Here's a strawman:

* Make ints 32 bits in Frog.

  • overflow checks in checked mode (throw error on overflow)
  • omit checks in unchecked mode (for best performance)

Provide a "long" type implemented in Dart that works for arbitrary length arithmetic.

Removed Type-Defect label.

Update spec_parser.
6826faf 
Update spec_parser to enable configurableUri in deferred imports,
make cascade syntax compositional, include `extension` declarations,
add `late` as a built-in identifier, and reorder the lexical rules for
single words such that they are grouped into reserved words, built-in
identifiers, and "other words known by the grammar".

Cf. language issue #615, #627, #628, #638.
