553ef1be94 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.

b0793f9741 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).

d15531b430 Now that iPTR is a fully resolved type. We end up losing the type check for
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

37efe67645 JumpTable support! What this represents is working asm and jit support for

PIC, and less dense forms of jump tables.
