3d4ab7a231 make AsmPrinter::doFinalization iterate over the global variables 
and call PrintGlobalVariable, allowing elimination and simplification
of various targets.

ac0f5e081e whitespace cleanups, make the MipsAsmPrinter::doInitialization 
chain to the super class instead of initializing mangler directly.
This gives it .file and module level inline asm support among other
things.

433fbf959a fix Sparc, SystemZ, and MSP430 to not override AsmPrinter::doInitialization. 
This eliminates redundancy setting up the mangler and adds support to them
for module-level inline asm and a .file directive.

- SYSEXIT64 (system call exit instruction to 64-bit user code) [REX.W 0f 35]
- SYSRET (system call return instruction) [0f 07]

ee3f2d6dc3 Make sure a global matching asm 'i' constraint gets its 
flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)

16a69eeaeb Pass in the unfortunately named "LessPrivatePrefix" for the 
"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...

1a10a060cb Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

5208843938 Don't override LowerArguments in the SPARC backend. In addition to 
being more consistent with other backends, this makes the SPARC backend 
deal with functions with arguments with illegal types correctly, which 
fixes some tests in test/CodeGen/Generic.

e208ce316a Switch Alpha over to the new call lowering style. New code mostly 
copied from the SystemZ target.  I don't think this causes any 
significant changes to the output (I compared the assembly, and the 
results appeared to be essentially unchanged), although I don't actually 
have an Alpha to test on.

I would appreciate if anyone with the appropriate hardware could test 
this. I'm not sure if that includes anyone subscribed to llvm-commits, 
though.
