98649d1796 In emitting code for a GEP instr, iterate over GEPTypes because there is one
more operand in GEPOps than there are types in GEPTypes: the pointer that is the
first operand of the GEP instruction.

c7fd0f4675 Use correct add*Imm form in more BuildMI calls.

Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.

2636c1be17 *FINALLY* Fix a really nasty nondeterministic bug that has been haunting us
since May 1st.  In this code, the pred iterator was being invalidated sometimes
causing the wrong entries to be added to PHI nodes.

The fix for this is to defererence and safe the *PI value before we hack on
branch instructions, which changes use/def chains, which SOMETIMES invalidates
the iterator.

63168d2244 Do not let the numbering of PHI nodes placed in the function depend on
non-deterministic things like the ordering of blocks in the dominance
frontier of a BB.  Unfortunately, I don't know of a better way to solve
this problem than to explicitly sort the BB's in function-order before
processing them.  This is guaranteed to slow the pass down a bit, but
is absolutely necessary to get usable diffs between two different tools
executing the mem2reg or scalarrepl pass.

Before this, bazillions of spurious diff failures occurred all over the
place due to the different order of processing PHIs:

-       %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.0, uint 0, uint 0
+       %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.1, uint 0, uint 0

Now, the diffs match.

1654cff8e8 Do not sort by the address of LLVM ConstantInt* objects. This produces
nondeterministic results that depend on where these objects land in memory.
Instead, sort by the value of the constant, which is stable.

Before this patch, the -simplifycfg pass run from two different compilers
could cause different code to be generated, though it was semantically the
same:

@@ -12258,8 +12258,8 @@
