This commit starts to add a page of microbenchmarks for wasm-bindgen
which we can hopefully track and compare over time. Right now it's
primarily focused on data collection, making it easy to collect data
across a number of benchmarks for comparison. It doesn't currently do
much in the way of actually comparing the results for you (aka drawing
pretty graphs), so let's left for a future step.
It's hoped though that we can use this to track performance improvements
as well as ensuring that they work over time!
This commit switches CI for the wasm-bindgen repository from a mixture
of Travis and AppVeyor to Azure Pipelines. One of the main reasons for
this was for me to personally get familiar with Azure Pipelines, but
after finishing it I think that this'd be a good transition for this
repository anyway.
With azure pipelines we're able to get more parallelism (10 vs the 3 on
Travis plus 1 on AppVeyor) as well as house all configuration in the
same location for one service (Azure Pipelines covers all 3 major
platforms).
I've tested this a good deal on my own personal repository as well, and
I believe that this is a lossless representation of our current CI,
releases and all!
