Richard Smith 3763d0130a Convert literals to i32 when forming an i32-typed int_literal instruction. (#3814) 
This is temporary: eventually per the design we should be forming
integer literals whose types reflect their values. But for now we should
ensure that values fit within their types.

This also fixes canonicalization of integer constants and hence of array
types, because we no longer have multiple different representations of
each `i32` value depending on the bit-width used for the literal.
