Compiler: continuing refactoring

Moving the arena memory allocation mechanism into it's own class as
a prelude to cleaning up the MIR and LIR data structures.

Reworked bit vector as a class using placement new w/ the arena
allocator.

Reworked GrowableList as a class template using the new arena
allocator and renamed to GrowableArray.
