b8d2f550b8 Change the FoldingSetNodeID usage for objects which carry 
alignment and volatility information, such as loads and
stores, to reduce the number of integer values added to
the FoldingSetNodeID.

67ca6be16a Tablegen generated code already tests the opcode value, so it's not 
necessary to use dyn_cast in these predicates.

242330371b Change WriteTypeSymbolic/WriteAsOperand to return void instead of 
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.

d6664311ac Resurrect some ancient code to add spill ranges without attempting folding, remat, or splitting. This code has been updated to current APIs 
in so far as it compiles and, in theory, works, but does not take advantage of recent advancements.  For instance, it could be improved by using
MachineRegisterInfo::use_iterator.

5eca075b74 Rename some GC classes so that their roll will hopefully be clearer. 
In particular, Collector was confusing to implementors. Several
thought that this compile-time class was the place to implement
their runtime GC heap. Of course, it doesn't even exist at runtime.
Specifically, the renames are:

  Collector               -> GCStrategy
  CollectorMetadata       -> GCFunctionInfo
  CollectorModuleMetadata -> GCModuleInfo
  CollectorRegistry       -> GCRegistry
  Function::getCollector  -> getGC (setGC, hasGC, clearGC)

Several accessors and nested types have also been renamed to be
consistent. These changes should be obvious.

fad86b003a Rework the routines that convert AP[S]Int into a string. Now, instead of 
returning an std::string by value, it fills in a SmallString/SmallVector
passed in.  This significantly reduces string thrashing in some cases.

More specifically, this:
 - Adds an operator<< and a print method for APInt that allows you to 
   directly send them to an ostream.
 - Reimplements APInt::toString to be much simpler and more efficient
   algorithmically in addition to not thrashing strings quite as much.

This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter.  This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

488dc6732d The pass manager is not able to schedule -loop-deletion -loop-index-split. 
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

c1f1d46f00 Replace two for loops with while(!X->use_empty()) loops. This prevents 
invalidating the iterator by deleting the current use. This fixes a segfault on
64 bit linux reported in PR2675.

Also remove an unneeded if.

739e441311 Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT node 
is lowered properly and covers everything LowerSELECT_CC did.
Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This
avoid the ugly instruction by instruction checking in printOperand.
Added a swap instruction present in the allegrex core.
Added two conditional instructions present in the allegrex core : MOVZ and MOVN.
They both allow a more efficient SELECT operation for integers.
Also added SELECT patterns to optimize MOVZ and MOVN usage.
The brcond and setcc patterns were cleaned: redundant and suboptimal patterns
were
removed. The suboptimals were replaced by more efficient ones.
Fixed some instructions that were using immZExt16 instead of immSExt16.

50dd1d0280 Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.
