Move initialization to compile time

[Eli Zaretskii]

Revision 109096 on the trunk moved some initializations from startup
(in temacs) to compile time.  Example:

AFAIK, this moves interval_block_index from the .bss section to .data
section.  If I'm right, then perhaps such changes should be discussed
before they are committed.
