Can't trust NodeDepth when checking for possibility of load folding creating
...
a cycle. This increase the search space and will increase compile time (in
practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec)
that will be addressed later.

Fixed a really ugly bug. The TableGen'd isel is not freeing the "inflight set"
...
correctly. That is causing non-deterministic behavior (and possibly preventing
some load folding from happening).

patterns that look like this:
def : Pat<(i32 (X86Wrapper tconstpool :$dst)), (MOV32ri tconstpool :$dst)>;
