4f41b86e7f Emit pic jumptables to the same section that the function is emitted to,
allowing label differences to work.  This fixes CodeGen/X86/pic_jumptable.ll

11590ccf0c Use $( $| $) to represent alternatives in asm blocks instead of {|}. This
is needed to support targets where {|} aren't special symbols.

ddf92db1ca Add support for ${:comment}, which expands to the current target's comment
character, and ${:uid} which expands to a unique ID for the MachineInstr.
More can be added if/when they are needed.

because they have an aggressive linker that does dead code stripping.

0e92042770 Emit .set directives for jump table entries when possible, which reduces
the number of relocations in object files, shrinkifying them.

557d3cacbe Instead of blindly looking past constantexpr casts, actually constant
fold them.  This correctly truncates constants that are too large for the
destination slot and makes the code easier to understand.  This fixes PR853
and Regression/CodeGen/X86/2006-07-28-AsmPrint-Long-As-Pointer.ll

0dc7ed966c Was pointed out that structure alignment and type alignment are not the same
thing.  Doubles still need to be special cased.

TargetData.h.  This should make recompiles a bit faster with my current

71bc529dfa Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

7ed816f900 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
