/* Rewriting a function into SSA form can create a huge number of SSA_NAMEs,
many of which may be thrown away shortly after their creation if jumps
were threaded through PHI nodes.
While our garbage collection mechanisms will handle this situation, it
is extremely wasteful to create nodes and throw them away, especially
when the nodes can be reused.
For PR 8361, we can significantly reduce the number of nodes allocated
and thus the total amount of memory allocated by managing SSA_NAMEs a
little. This additionally helps reduce the amount of work done by the
garbage collector. Similar results have been seen on a wider variety
of tests (such as the compiler itself).
Right now we maintain our free list on a per-function basis. It may
or may not make sense to maintain the free list for the duration of
a compilation unit.
External code should rely solely upon HIGHEST_SSA_VERSION and the
externally defined functions. External code should not know about
the details of the free list management.
External code should also not assume the version number on nodes is
monotonically increasing. We reuse the version number when we
reuse an SSA_NAME expression. This helps keep arrays and bitmaps
more compact. */
