Cache PrecompilationIds for a nice little speedup
Cache PrecompilationIds for a nice little speedup

Since PrecompilationIds are immutable, we can cache them without doing any
harm. This saves a lot of re-checking of id strings as for example the
compiler-id is passed around a lot.

Brings GTK::Simple's loading time from 260ms to 227ms, saving another 13 %.
