How much of a performance gain does unboxed floats and 3 tag bits represent
specifically for the compiler? Ie, if someone makes sagnificant use of the
compiler would it not be better to pay the one-off (per install) cost of
bootstrapping the compiler? the gain is the multiple time improvements in
the compiler's performance.
