a43c86b354 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the 
expression to include the modifier.
 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.

3d4644bad9 Revert r114097, adding back in the assertion against replacing an Instruction by itself. Now that CorrelatedValuePropagation is 
more careful not to call SimplifyInstructionsInBlock() on an unreachable block, the issue has been fixed at a higher level.  Add
a big warning to SimplifyInstructionsInBlock() to hopefully prevent this in the future.

cf9dc14249 When substituting sunkaddrs into indirect arguments an asm, we were 
walking the asm arguments once and stashing their Values.  This is
wrong because the same memory location can be in the list twice, and
if the first one has a sunkaddr substituted, the stashed value for the
second one will be wrong (use-after-free).  PR 8154.

6f3516065f It is possible, under specific circumstances involving ptrtoint ConstantExpr's, for LVI to end up trying to merge 
a Constant into a ConstantRange.  Handle this conservatively for now, rather than asserting.  The testcase is
more complex that I would like, but the manifestation of the problem is sensitive to iteration orders and the state of the
LVI cache, and I have not been able to reproduce it with manually constructed or simplified cases.

Fixes PR8162.

68e2c15954 Change SPU register re-interpretations from OR to COPY_TO_REGCLASS instruction. 
This cleans up after the mess r108567 left in the CellSPU backend.
ORCvt-instruction were used to reinterpret registers, and the ORs were then
removed by isMoveInstr(). This patch now removes 350 instrucions of format:
	or $3, $3, $3
(from the 52 testcases in CodeGen/CellSPU). One case of a nonexistant or is
checked for.

Some moves of the form 'ori $., $., 0' and 'ai $., $., 0' still remain.

7321210916 Fix a threaded LLVM bug due the need for operator= on reference counted AttrListImpl's. It might 
be possible to implement this very carefully to allow a lock-free implementation while still
avoiding illegal interleavings, but I haven't been able to figure one out.

e37047a62f Use the value mapping provided by LiveIntervalMap. This simplifies the code a 
great deal because we don't have to worry about maintaining SSA form.

Unconditionally copy back to dupli when the register is live out of the split
range, even if the live-out value was defined outside the range. Skipping the
back-copy only makes sense when the live range is going to spill outside the
split range, and we don't know that it will. Besides, this was a hack to avoid
SSA update issues.

Clear up some confusion about the end point of a half-open LiveRange. Methinks
LiveRanges need to be closed so both start and end are included in the range.
The low bits of a SlotIndex are symbolic, so a half-open range doesn't really
make sense. This would be a pervasive change, though.

445e4de610 Since PassRegistry is currently a shared global object, it needs locking. While it might intuitively seem 
that all the setup of this class currently happens at static initialization time, this misses the fact
that some later events can cause mutation of the PassRegistrationListeners list, and thus cause race issues.
