Subject: [PATCH] increase tracelog buffer sizes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise a lot of the benchmarks trigger errors and warnings about lost
events, for example (pardon my french ...xperf):

```
xperf: error: rustc-perf-counters: Le nom d'instance passé n'a pas été
reconnu valide par un fournisseur de données WMI. (0x1069).
xperf: warning: Session "rustc-perf-counters" lost 5204 events.
```
