Gregory Szorc ae7cf57366 Bug 1411081 - Move --enable-optimize/MOZ_OPTIMIZE to moz.configure; r=glandium
The Rust optimization logic is tied to --enable-optimize/MOZ_OPTIMIZE
and --enable-debug/MOZ_DEBUG. In order to more easily implement more
customization, let's move --enable-optimize/MOZ_OPTIMIZE to
moz.configure so its value can be consulted there.

The logic here is a bit wonky. The option behaves like a boolean
or a string. If a string, MOZ_OPTIMIZE is set to 2. Otherwise it
is 1 or unset depending on the boolean value.

The custom compiler flags string is passed to old-configure, where it
overwrites whatever old-configure derived as the default value.
We stop short of moving all references to MOZ_OPTIMIZE_FLAGS to
moz.configure because there are a handful of them and I don't want
to scope bloat.
