avanhatt opened PR #6078 from iconst-imm12 to main:

Fixes https://github.com/bytecodealliance/wasmtime/issues/5903

This fixes imm12_from_negated_value to correctly sign-extend narrow values before negating them as i64 values, allowing these rules to work for non-zero negative i32 and i16.

As suggested by @jameysharp in that issue, switch imm12_from_negated_value to be a partial term with a corresponding rule.

Also updated + added to the relevant filetest.
