    [heap] Initialize pages with placement-new · a8471820
    Dominik Inführ authored
    Define ctors for BasicMemoryChunk, ReadOnlyPage, MemoryChunk, Page and
    LargePage. We can use those with placement-new to initialize pages. We
    now initialize chunks at once either for ReadOnlyPage, Page or
    LargePage. Previously initialization happened in multiple locations
    starting with BasicMemoryChunk::Initialize.
    
    Adding ctors to these classes should improve debugging, since debug
    info for classes without ctors was removed with the compiler flag
    `-fuse-ctor-homing`.
