    • Convert LTO type hashing to the new inchash interface · 0bd8bb04 
      Should not really change any behavior, it's just a more abstract

    • Add an abstract incremental hash data type · 6d8eb96b 
      Some files in gcc, like lto or tree, do large scale incremential hashing.
The current jhash implementation of this could be likely improved
by using an incremential hash that does not do a full rehashing
for every new value added.

This patch adds a new "inchash" class that abstracts the internal
state of the hash. This makes it easier to plug in new hashes
and also cleans up the code a bit.

Right now it is just implemented in the same way as the old
iterative hash in tree.c. The previous iterative hash code
from tree.c moved into a new separate file. Also I fixed up all
users to include the new header.

It should not really significantly change any hashing by itself,
it's mostly a cleanup at this point.

v2: Remove begin. Add commutative interface.
Add merge hash interface.  Add add_flag.
