type is the same as the element type of the vector.  EXTRACT_VECTOR_ELT can
be used to extended the width of an integer type.  This fixes a bug for
Generic/vector-casts.ll on a ppc750.

fashion, and if they don't have an ordering set, then give it one.

This allows code gen and the exception table writer to cooperate to make sure
landing pads are associated with the correct invoke locations.

runOnMachineFunction, and switch PPC to use EmitFunctionBody.
The two ppc asmprinters now don't heave to define 
runOnMachineFunction.

"0" is nice and target independent.

Move the X86 implementation of function body emission up to 
AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

Overload it in the ARM backend to do nothing, since is does insane
constant pool emission.

let that stop it from being deleted, and change the

which allows targets to override function entry label emission.
Use it to convert linux/ppc to use EmitFunctionHeader().

Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

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.

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.

subsumed by TargetLowering::getJumpTableEncoding().  Change uses of

inline it into its only caller, allowing us to simplify it
and hoist bits out of the loop.

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.

use it to implement the default TargetLowering::getPICJumpTableRelocBaseExpr
