Flaky compiler OOM when compiling files with long eventuals pipelines

[CodingCanuck]

Per #275 (comment) , it looks like we're seeing flaky compilation failures of files like test/grpc/streaming.cc. That file is interesting because it contains multiple long eventuals pipelines which have previously caused slow compilation: #275

Googling the error message makes me think that these failures are caused by the compiler running out of memory when trying to compile complicated code. I'm further suspicious that this is happening when we're building with --config=asan, since my unsubstantiated impression is that compilers perform worse (slower, use more resources) when compiling in non-standard modes (like asan or other sanitizers) vs. in standard modes.
