This patch adds the following API for tools to enable compile
cache dynamically and query its status.
- module.enableCompileCache(cacheDir)
- module.getCompileCacheDir()
In addition this adds a NODE_DISABLE_COMPILE_CACHE environment
variable to disable the code cache enabled by the APIs as
an escape hatch to avoid unexpected/undesired effects of
the compile cache (e.g. less precise test coverage).
When the module.enableCompileCache() method is invoked without
a specified directory, Node.js will use the value of
the NODE_COMPILE_CACHE environment variable if it's set, or
defaults to `path.join(os.tmpdir(), 'node-compile-cache')`
otherwise. Therefore it's recommended for tools to call this
method without specifying the directory to allow overrides.
