Introduce a new node for holding call argument
flags.  This is needed by the new legalize types
infrastructure which wants to expand the 64 bit
constants previously used to hold the flags on
32 bit machines.  There are two functional changes:
(1) in LowerArguments, if a parameter has the zext
attribute set then that is marked in the flags;
before it was being ignored; (2) PPC had some bogus
code for handling two word arguments when using the
ELF 32 ABI, which was hard to convert because of
the bogusness.  As suggested by the original author
(Nicolas Geoffray), I've disabled it for the moment.

Fixed a coalescer bug caused by a typo.

Fix live variables issues:
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
   = EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.

On Darwin, GCC issues a ".globl" for something that has a "visibility protected"
attribute instead of ".protected".

Fix a x86-64 isel lowering bug that's been around forever. A x86-64 varargs function implicitly reads X86::AL, don't clobber it!

Note that gcc 4.0.1 will trip internal LLVM asserts (e.g., pred_iterator) if compiling
for Release with optimization levels greater than -O0.

It might be nice to have this run as x86 on non-x86 platforms...

Do not pass -g flag when compiling tests, so remove the C.Flags. This only happens if you have a debug build of llvm.
