Bruno Cardoso Lopes 7d5d402b16 Fixed call stack alignment. Improved AsmPrinter alignment issues.

Bruno Cardoso Lopes 80ab8f9649 Added Subtarget support into RegisterInfo
Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and 
-mno-shared). HasAbsoluteCall is not implemented but HasABICall is the 
default for o32 ABI. Now, both should help into a more accurate 
relocation types implementation. 
Added IsLinux is needed to choose between asm directives.
Instruction name strings cleanup.
AsmPrinter improved.

Bruno Cardoso Lopes c9c3f49993 Several changes to Mips backend, experimental fp support being the most
important.
- Cleanup in the Subtarget info with addition of new features, not all support
  yet, but they allow the future inclusion of features easier. Among new features,
  we have : Arch family info (mips1, mips2, ...), ABI info (o32, eabi), 64-bit
  integer
  and float registers, allegrex vector FPU (VFPU), single float only support.
- TargetMachine now detects allegrex core.
- Added allegrex (Mips32r2) sext_inreg instructions.
- *Added Float Point Instructions*, handling single float only, and
  aliased accesses for 32-bit FPUs.
- Some cleanup in FP instruction formats and FP register classes.
- Calling conventions improved to support mips 32-bit EABI.
- Added Asm Printer support for fp cond codes.
- Added support for sret copy to a return register.
- EABI support added into LowerCALL and FORMAL_ARGS.
- MipsFunctionInfo now keeps a virtual register per function to track the
  sret on function entry until function ret.
- MipsInstrInfo FP support into methods (isMoveInstr, isLoadFromStackSlot, ...),
  FP cond codes mapping and initial FP Branch Analysis.
- Two new Mips SDNode to handle fp branch and compare instructions : FPBrcond,
  FPCmp
- MipsTargetLowering : handling different FP classes, Allegrex support, sret
  return copy, no homing location within EABI, non 32-bit stack objects
  arguments, and asm constraint for float.

Dale Johannesen ce4396bc92 Add CommonLinkage; currently tentative definitions
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

Evan Cheng c799065cc3 Add a quick and dirty "loop aligner pass". x86 uses it to align its loops to 16-byte boundaries.

Bill Wendling c24ea4fb41 Change "Name" to "AsmName" in the target register info. Gee, a refactoring tool
would have been a Godsend here!

Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types:
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Bruno Cardoso Lopes 3e0d030dad Added support for PIC code with "explicit relocations" *only*.
Removed all macro code for PIC (goodbye "la").
Support tested with shootout bench.

Duncan Sands 283207a71c Eliminate the remaining uses of getTypeSize. This
should only effect x86 when using long double.  Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment).  This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.

Dan Gohman dc35bd79ca Change the names used for internal labels to use the current
function symbol name instead of a codegen-assigned function
number.

Thanks Evan! :-)
