Get the adjusted file load size (i.e., filtered load size) to be loaded into memory block which relates to 
this program header; it may be zero if no block should be created.  The returned value reflects any adjustment 
the ElfExtension may require based upon the specific processor/language implementation which may 
require filtering of file bytes as loaded into memory.
@return the number of bytes to be loaded into the resulting memory block
