Splits into 4 jobs: gn linux, gn mac, cargo linux, LSAN linux.

The 'script' key in the deploy section that is supposed to run the
benchmarks isn't doing anything. Because of this, Travis bumps its head
when trying to deploy a non-existing directory to github pages, which
makes that our master branch is now consistently red.

This patch restores the setup that worked before.

This partially reverts commit aa66ef98.

This avoids accidentally leaking the key in the build log.

Adds prebuilt hyperfine and sccache binaries 

Only build test_cc for LSAN

Add Cargo.lock

Only run benchmarks in master
