a266197489 Switch from using an ilist for uses to using a custom doubly linked list. 
This list does not provide the ability to go backwards in the list (its
more of an unordered collection, stored in the shape of a list).

This change means that use iterators are now only forward iterators, not
bidirectional.

This improves the memory usage of use lists from '5 + 4*#use' per value to
'1 + 4*#use'.  While it would be better to reduce the multiplied factor,
I'm not smart enough to do so.  This list also has slightly more efficient
operators for manipulating list nodes (a few less loads/stores), due to not
needing to be able to iterate backwards through the list.

This change reduces the memory footprint required to hold 176.gcc from
66.025M -> 57.687M, a 14% reduction.  It also speeds up the compiler,
7.73% in the case of bytecode loading alone (release build loading 176.gcc).

a9548d9fd9 * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

02accaeb17 Adjust to ilist changes. 
Based on the ilist changes avoid allocating an entire Use object for the
end of the Use chain.  This saves 8 bytes of memory for each Value allocated
in the program.  For 176.gcc, this reduces us from 69.5M -> 66.0M, a 5.3%
memory savings.

5ae3571f75 This file was schizophrenic when it came to representing sizes. In some 
cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.
