We have two API entries for native compilation: `native-compile'
(synchronous) and `native-compile-async' (indeed asynchronous).
Deferred compilation is the mechanism to trigger automatically an async
native compilation (through `native-compile-async') for bytecodes being
loaded when the native code is not present (+ have the hotswap performed
when finished native compiling).

Sorry for the sloppy answer this morning I was rushing :/ Looking at it
my subr-x.eln is pretty much big the same (the factor depends on the
single file). I believe in general bytecode is a more compact
representation than native code.
