Chris Lattner b5c5160a55 eliminate all forms of addPassesToEmitMachineCode except 
the one used by the JIT.  Remove all forms of
addPassesToEmitFileFinish except the one used by the static
code generator.  Inline the remaining version of
addPassesToEmitFileFinish into its only caller.

Chris Lattner 0823d2a654 Inline addAssemblyEmitter into its one real caller and delete 
the -print-emitted-asm option.  The JIT shouldn't have to pull
in the asmprinter.

Chris Lattner 39ceb471b7 don't turn (A & (C0?-1:0)) | (B & ~(C0?-1:0)) -> C0 ? A : B 
for vectors.  Codegen is generating awful code or segfaulting
in various cases (e.g. PR6204).

Chris Lattner d569561835 fix rdar://7590304, a miscompilation of objc apps on arm. The caller 
of objc message send was getting marked arm_apcscc, but the prototype
isn't.  This is fine at runtime because objcmsgsend is implemented in
assembly.  Only turn a mismatched caller and callee into 'unreachable'
if the callee is a definition.

Chris Lattner 830f3f205d fix rdar://7590304, an infinite loop in instcombine. In the invoke 
case, instcombine can't zap the invoke for fear of changing the CFG.
However, we have to do something to prevent the next iteration of
instcombine from inserting another store -> undef before the invoke
thereby getting into infinite iteration between dead store elim and
store insertion.

Just zap the callee to null, which will prevent the next iteration
from doing anything.

AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

Chris Lattner 111a3193b5 use EmitLinkage for functions as well as globals. One output 
change is that we now use ".linkonce discard" for global variables
instead of ".linkonce samesize".  These should be the same, just less
strict.  If anyone is interested in mcizing MCSection for COFF targets,
this should be easy to fix.

Chris Lattner cee63322ea Eliminate SetDirective, and replace it with HasSetDirective. 
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

Chris Lattner 589c6f620e Move getJTISymbol from MachineJumpTableInfo to MachineFunction, 
which is more convenient, and change getPICJumpTableRelocBaseExpr
to take a MachineFunction to match.

Next, move the X86 code that create a PICBase symbol to
X86TargetLowering::getPICBaseSymbol from 
X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific 
library.  This eliminates a 'gross hack', and allows us to
implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
calls it.

This in turn allows us to eliminate the 
X86AsmPrinter::printPICJumpTableSetLabel method, which was the
only overload of printPICJumpTableSetLabel.

Chris Lattner e35df92eca simplify asmprinter: only emit .set directives when entries have 
EK_LabelDifference32 kind and the target has .set support.  Simplify
X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers.

Chris Lattner c64daabb70 implement X86 @GOTOFF jump table entries with the new EK_Custom32 
jump table entry kind, instead of overloading 
AsmPrinter::printPICJumpTableEntry.

This has a pretty horrible and inefficient FIXME around how @GOTOFF
is currently smashed into the mcsymbol name, but otherwise this is
much cleaner.

Chris Lattner 071c62fad0 Rearrange handling of jump tables. Highlights: 
1. MachineJumpTableInfo is now created lazily for a function the first time
   it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
   MachineJumpTableInfo::JTEntryKind enum.  This enum is determined by the
   TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
   throughout the compiler that "knows" that jump table entries are always
   32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
   their kind, instead of at machinefunction creation time.

Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.
