984c1a4a8f Emit .set directives for jump table entries when possible, which reduces 
the number of relocations in object files, shrinkifying them.

85492427f2 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

fd5a8ebb74 On 64-bit targets like ppc64, we should use .quad to output pointer directives, 
not .long.

ec1d60bd98 Add support to print 4-, 8-, and 16- byte constant literals in special 
sections. e.g. On Darwin that would be .literal4 and .literal8.

3519b87758 Was pointed out that structure alignment and type alignment are not the same 
thing.  Doubles still need to be special cased.

dce07568f2 Alignment of globals has not been quite right. Needed to drop the pointer type 
to get the alignment of the element type.

8c2c1e90c4 Refactor a bunch of includes so that TargetMachine.h doesn't have to include 
TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

20a631fde7 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.

4ca2ea5b43 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.

aa23fa9f43 Implement smart printing of inline asm strings, handling variants and 
substituted operands.  For this testcase:

int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

we now emit:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz r2, r2, r3  ;; look here
        or r3, r2, r2
        blr

... note the substituted operands. :)
