Rollup merge of #64374 - nnethercote:box-DiagnosticBuilder, r=zackmdavis
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. The commit touches a lot of lines but it's almost all trivial plumbing changes.
