Subject: [PATCH] Print VerifierErrors in Display for CodegenResult

These seem to have gotten lost in the switch to `thiseerror`
(https://github.com/bytecodealliance/cranelift/commit/d23030f7f5ce75a89b31f260c9ea893530f0124a#diff-55f6fffe972a2ad7efb7edd56cb29afcR15)

That change made it very hard to debug bad generated code.
This change prints the message again.
