19680a4928 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 :)

fa884ac11b 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.

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

3. Simplify serialization of DebugDescInfo subclasses.

763d7462d5 More libcall transformations: 
printf("%s\n", str) -> puts(str)
printf("%c", c) -> putchar(c)
Also fixed fprintf(file, "%c", c) -> fputc(c, file)

that is currently just like ppc32 :)

82494a2bce 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.

48823987ff 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.

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

b28a9eedd3 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.

07d8ccec50 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.

1b42069db1 Use the PotDoms map to memoize 'dominating value' lookup. With this patch,
