Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks.

to fix up the type info pointers. It's better to place it into the __TEXT
section and use pc-rel indirect pointer encodings. Similar to the personality
routine.

Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that sdisel will use to properly complete phi nodes.

causes the "../foo" to not find the file

llvm-svn: 82270

getSymbolForDwarfGlobalReference is smart enough to know that it 
needs to register the stub it references with MachineModuleInfoMachO,
so that it gets emitted at the end of the file.

Move stub emission from X86ATTAsmPrinter::doFinalization to the
new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
thing here is that EmitEndOfAsmFile is called *after* the ehframes are
emitted, so we get all the stubs.

This allows us to remove a gross hack from the asmprinter where it would
"just know" that it needed to output stubs for personality functions.
Now this is all driven from a consistent interface.

The testcase change is just reordering the expected output now that the
stubs come out after the ehframe instead of before.

This also unblocks other changes that Bill wants to make.

Overriding doFinalization is pretty lame.

Update malloc call creation code (AllocType is now the element type of the malloc, not the resulting type).

In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.

Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.

Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.

Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.

Add verification for malloc calls.

Fix a bug in sdisel switch lowering code. When it updates the phi nodes in switch successor blocks, it can introduce multiple phi operands of the same value from different blocks (and may not be on the predecessor list).

This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).
