for a lazy accessor inside a method, make it check the initialization bitmap
for all methods, add enough int vars to allow one flag per lazy local value
blocks in template bodies behave almost like methods. A single bitmaps section is
added in the first block, for all lazy values defined in such blocks.
remove ACCESSOR flags: accessors in traits are not statically implemented,
but moved to the host class. local lazy values should be statically implemented.
Transform local lazy accessors to check for the initialized bit.
