Applying this patch to the Envoy submodule reverts split DWARF support in upstream envoy and allows the analysis documented in [Envoy Mobile](https://envoy-mobile.github.io/docs/envoy-mobile/latest/development/performance/binary_size.html). ```diff diff --git a/.bazelrc b/.bazelrc index c7a6e779b..5c57d6675 100644...

This PR https://github.com/envoyproxy/envoy-mobile/pull/2085 pulls in all of @alyssawilk's upstream changes.

recent dependency updates in Envoy have caused breakages in Envoy Mobile. This is another reason to run envoy mobile tests in Envoy CI.

These are all my current thoughts on this space. Nothing too fleshed out, but enough to get started. @buildbreaker I am assigning to you, as discussed internally, while I am...

After running a fresh analysis 10/2020 this issue continues to be the greatest investment we can make. Compiled protos account ~34% of the binary size so dropping v2 protos should...
