Reserved register live ranges look like a set of dead defs - any uses of
reserved registers are ignored.

Instead of skipping the updating of reserved register operands entirely,
just ignore the use operands and treat the def operands normally.

No test case, handleMove() is not commonly used yet.

of operand is specific to MS-style inline assembly and should not be generated
when parsing normal assembly.

The purpose of the wildcard operands are to allow the AsmParser to match
multiple instructions (i.e., MCInsts) to a given ms-style asm statement.  For
the time being the matcher just returns the first match.  This patch only
implements wildcard matches for memory operands.  Support for register
wildcards will be added in the near future.

JoinVals::pruneValues() calls LIS->pruneValue() to avoid conflicts when
overlapping two different values. This produces a set of live range end
points that are used to reconstruct the live range (with SSA update)
after joining the two registers.

When a value is pruned twice, the set of end points was insufficient:

  v1 = DEF
  v1 = REPLACE1
  v1 = REPLACE2
  KILL v1

The end point at KILL would only reconstruct the live range from
REPLACE2 to KILL, leaving the range REPLACE1-REPLACE2 dead.

Add REPLACE2 as an end point in this case so the full live range is
reconstructed.

This fixes PR13999.

We require that the indices into the use lists are stable in order to
build fast lookup tables to locate a particular partition use from an
operand of a PHI or select. This is (obviously in hind sight)
incompatible with erasing elements from the array. Really, we don't want
to erase anyways. It is expensive, and a rare operation. Instead, simply
weaken the contract of the PartitionUse structure to allow null Use
pointers to represent dead uses. Now we can clear out the pointer to
mark things as dead, and all it requires is adding some 'continue'
checks to the various loops.

I'm still reducing a test case for this, as the test case I have is
huge. I think this one I can get a nice test case for though, as it was
much more deterministic.

the linking stage. However, when we compile object files during LTO we don't
call 'dsymutil'. That's done at a different stage (if at all). We rely upon the
linker to specify a unique name for the temporary file it generates.

being separate was that it can grow the use list. As a consequence, we
can't use the iterator-pair interface, we need an index based interface.
Expose such an interface from the AllocaPartitioning, and use it in the
speculator.

This should at least fix a use-after-free bug found by Duncan, and may
fix some of the other crashers.

I don't have a nice deterministic test case yet, but if I get a good
one, I'll add it.
