Box `DiagnosticBuilder`.
It's a large type -- 176 bytes on 64-bit. And it's passed around and returned from a lot of functions, including within PResult. This commit boxes it, which reduces memory traffic. In particular, `PResult` shrinks to 16 bytes in the best case; this reduces instruction counts by up to 2% on various workloads.
