Bazel configuration for RBE
Necessary configuration to allow building IREE with RBE. This should eventually allow much faster continuous builds.
With these changes, I am able to run:
`bazel test --config=rbe -- //iree/... -//iree/hal/vulkan:dynamic_symbols_test -//iree/samples/rt:bytecode_module_api_test`
and all tests pass. The two explicit excludes are tests that rely on vulkan (so are going to need a custom toolchain or GPU executors).
For now I'm the only one actually authorized to do that, but auth improvements coming soon :-D
I decided to unconditionally add the --experimental_guard_against_concurrent_changes and remove the advice to add it to user.bazelrc. I'm pretty sure this flag does nothing without some caching mechanism provided and is slated to be switched to default true anyway.
Closes #181
