Jim Grosbach 54c0530834 Update of 94055 to track the IR level call site information via an intrinsic.
This allows code gen and the exception table writer to cooperate to make sure
landing pads are associated with the correct invoke locations.

Chris Lattner 73de5fbfc3 Give AsmPrinter the most common expected implementation of
runOnMachineFunction, and switch PPC to use EmitFunctionBody.
The two ppc asmprinters now don't heave to define 
runOnMachineFunction.

Chris Lattner 565896b9eb emit a 0 byte instead of a noop if a function is empty on darwin.
"0" is nice and target independent.

Chris Lattner 94a946cac4 Remove the argument from EmitJumpTableInfo, because it doesn't need it.
Move the X86 implementation of function body emission up to 
AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

Chris Lattner 2b796241a7 Drop the argument to AsmPrinter::EmitConstantPool and make it virtual.
Overload it in the ARM backend to do nothing, since is does insane
constant pool emission.

Chris Lattner bc1e6f0873 add a new AsmPrinter::EmitFunctionEntryLabel virtual function,
which allows targets to override function entry label emission.
Use it to convert linux/ppc to use EmitFunctionHeader().

Chris Lattner fc2e376a15 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 c7b91156e4 now that enough stuff is constified, move function header printing
logic up from X86 into the common code.  The other targets will 
hopefully start using this soon.

Chris Lattner ff234e09b9 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 3dd38a8112 eliminate MCAsmInfo::NeedsSet: we now just use .set on any platform
that has it.

Chris Lattner 547c761dd6 eliminate the TargetLowering::UsesGlobalOffsetTable bool, which is
subsumed by TargetLowering::getJumpTableEncoding().  Change uses of
it to be more specific.

Chris Lattner 4db603f93b Now that printPICJumpTableSetLabel is not overloaded,
inline it into its only caller, allowing us to simplify it
and hoist bits out of the loop.

Chris Lattner 8a785d7a67 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 cc0f734cd0 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 279de3ef64 rename printPICJumpTableEntry -> EmitJumpTableEntry,
make it private and non-virtual.  It handles the non-pic
case too, so just use it, simplifying EmitJumpTableInfo.

Chris Lattner 6715952c25 make MachineFunction keep track of its ID and make
MachineFunctionAnalysis dole them out, instead of having
AsmPrinter do both.  Have the AsmPrinter::SetupMachineFunction
method set the 'AsmPrinter::MF' variable.

Chris Lattner b6db2c6b31 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.

Chris Lattner 76bdea3290 resolve a fixme: the "nonexecutable stack directive" is actually
a .section.  Switch to it with SwitchSection.

However, I think that this directive should be safe on any ELF target.
If so, we should hoist it up out of the X86 and SystemZ targets.
