bf8e5204d1 Update these argument lists for the isNormalMemory 
argument. This doesn't affect current functionality.

79c3516912 Use a latency value of 0 for the artificial edges inserted by 
AddPseudoTwoAddrDeps. This lets the scheduling infrastructure
avoid recalculating node heights. In very large testcases this
was a major bottleneck. Thanks to Roman Levenstein for finding
this!

As a side effect, fold-pcmpeqd-0.ll is now scheduled better
and it no longer requires spilling on x86-32.

problem, rather than fixing it.  The problem has now been fixed the right way.

ac79602005 The llvm::ELFWriter::EmitGlobal() method is calling the 
llvm::PATypeHolder::get() method when LLVM is self-hosted in Release
mode. Before the parser changed, there was a definition of llvm::PAHolder::get()
in llvmAsmParser.y. This was probably a bug that no-one noticed.

Explicitly #include the Type.h file as a temporary fix for now.

1be2e9650e Remove the code from the scheduler that commuted two-address 
instructions to avoid copies, because TwoAddressInstructionPass
also does this optimization.  The scheduler's version didn't
account for live-out values, which resulted in spurious commutes
and missed opportunities.

Now, TwoAddressInstructionPass handles all the opportunities,
instead of just those that the scheduler missed. The result is
usually the same, though there are occasional trivial differences
resulting from the avoidance of spurious commutes.

8feb694e8f Fix PR3274: when promoting the condition of a BRCOND node, 
promote from i1 all the way up to the canonical SetCC type.
In order to discover an appropriate type to use, pass
MVT::Other to getSetCCResultType.  In order to be able to
do this, change getSetCCResultType to take a type as an
argument, not a value (this is also more logical).

12f2490489 Clean up the atomic opcodes in SelectionDAG. 
This removes all the _8, _16, _32, and _64 opcodes and replaces each
group with an unsuffixed opcode. The MemoryVT field of the AtomicSDNode
is now used to carry the size information. In tablegen, the size-specific
opcodes are replaced by size-independent opcodes that utilize the
ability to compose them with predicates.

This shrinks the per-opcode tables and makes the code that handles
atomics much more concise.

072e52f170 Use isTerminator() instead of isBranch()||isReturn() in 
several places. isTerminator() returns true for a superset
of cases, and includes things like FP_REG_KILL, which are
nither return or branch but aren't safe to move/remat/etc.
