16682fff2b Document the subtarget features better, make sure that 64-bit mode, 64-bit 
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

a35f306740 Rename some subtarget features. A CPU now can *have* 64-bit instructions, 
can in 32-bit mode we can choose to optionally *use* 64-bit registers.

b2ff2d481e 1. Revise vector debug support. 
2. Update docs for vector debug support and new version control.

3. Simplify serialization of DebugDescInfo subclasses.

1fc4025a9c More libcall transformations: 
printf("%s\n", str) -> puts(str)
printf("%c", c) -> putchar(c)
Also fixed fprintf(file, "%c", c) -> fputc(c, file)

0c4aa14deb First baby step towards ppc64 support. This adds a new -march=ppc64 backend 
that is currently just like ppc32 :)

57e8e38a6f Only print the stack trace if it was requested. Previously, any call into 
the Signals module that registered the handlers would cause the stack trace
to be generated. Now, you must explicitly call PrintStackTraceOnErrorSignal
in order for that to happen.

4ff6c1646f Teach the local allocator to know that live-in values (e.g. arguments) are 
live at function entry.  This prevents it from using arg registers for other
purposes before the arguments are used.

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

aba6398f8b Actually add instructions to the list of defined values so it gets 
recognized as such!  This prevents the CppWriter from treating every
operand as a forward reference and making a mess of the output.

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

55772ccfd6 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

e3abb14503 Use the PotDoms map to memoize 'dominating value' lookup. With this patch, 
LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes
39s instead of 289s. :)
