Restore r26192, r26240, r26241:  All three about implicit-array sizing design and implementation.  *Minus* test results.

r26192: Link-time sizing of implicitly-sized arrays and handling of anonymous blocks containing implicitly-sized members.  Also changed "__anon" to "anon@" and encapsulated it.

r26240: Solidify the sharing of struct and array information between nodes and variables: A single copy now allows for simultaneously setting array size for all effected nodes and symbols of a given type. This allowed removal of ioArrayNodeResizeList and makes nodes of implicitly sized arrays know the final size.

r26241: Fix g++ issue with wanting non-const iterator.
