ffbd0715fa Increment DFAStateEntryTable index for sentinel entry.
When adding the {-1, -1} entry to the DFAStateInputTable, we
need to increment the index used to populate the DFAStateEntryTable.
Otherwise, the entry table will be off by one for each transition
after the {-1, -1} entry. PR11908.

1aee22e072 Replace the old --with-cxx-* configure options with a single --with-gcc-toolchain
that just uses the new toolchain probing logic. This fixes linking with -m32 on
64 bit systems (the /32 dir was not being added to the search).

b5af2d943e Specify SubRegIndex components on the index itself.
It is simpler to define a composite index directly:

  def ssub_2 : SubRegIndex<[dsub_1, ssub_0]>;
  def ssub_3 : SubRegIndex<[dsub_1, ssub_1]>;

Than specifying the composite indices on each register:

  CompositeIndices = [(ssub_2 dsub_1, ssub_0),
                      (ssub_3 dsub_1, ssub_1)] in ...

This also makes it clear that SubRegIndex composition is supposed to be
unique.

ee599209e6 Fix a bug in the TopoOrderRC comparison function.
The final tie breaker comparison also needs to return +/-1, or 0.
This is not a less() function.

This could cause otherwise identical super-classes to be ordered
unstably, depending on what the system qsort routine does with a bad
compare function.

0c6e177881 Remove Deprecated Features
Move to a model where we build whatever branches are checked out
in the source directories.  This was a bit too smart (and complicated)
in handling details best left to the user and the revision control
system.

In addition, get rid of support for llvm-gcc and building gcc as
these are no longer necessary.

Unfortunately I don't think there's a fix for this that will work upstream and
also satisfy Clang's -Wunreachable-code, which is a pity. But I'll give it some
more thought -perhaps there's some way out.

164b86b439 Extend Attributes to 64 bits
Problem: LLVM needs more function attributes than currently available (32 bits).
One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc).

Solution:
- extend the Attributes from 32 bits to 64-bits
- wrap the object into a class so that unsigned is never erroneously used instead
- change "unsigned" to "Attributes" throughout the code, including one place in clang.
- the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking.
- the class has "safe operator bool()" to support the common idiom:  if (Attributes attr = getAttrs()) useAttrs(attr);
- The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls
- Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work.
- Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit.

Tested:
"make check" on Linux (32-bit and 64-bit) and Mac (10.6)
built/run spec CPU 2006 on Linux with clang -O2.


This change will break clang build in lib/CodeGen/CGCall.cpp.
The following patch will fix it.

31867660cb Add a CoveredBySubRegs property to Register descriptions.
When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.

f61f22a5d1 Add an LLDB data formatter script for llvm::SmallVector, maybe this is helpful to someone else.
This lets lldb give sane output for SmallVectors, e.g.
Before:
(lldb) p sv
(llvm::SmallVector<int, 10>) $0 = {
  (llvm::SmallVectorImpl<int>) llvm::SmallVectorImpl<int> = {
    (llvm::SmallVectorTemplateBase<int>) llvm::SmallVectorTemplateBase<int> = {
      (llvm::SmallVectorTemplateCommon<int>) llvm::SmallVectorTemplateCommon<int> = {
        (llvm::SmallVectorBase) llvm::SmallVectorBase = {
          (void *) BeginX = 0x00007fff5fbff960
...
}

After:
(lldb) p sv
(llvm::SmallVector<int, 10>) $0 = {
  (int) [0] = 42
  (int) [1] = 23
...
}

The script is still a bit rough so expect crashes for vectors of complex types.
Synthetic children are _not_ available in xcode 4.2, newer LLDBs should work though.

82f000266a Fix TableGen so that it will emit the correct signature for FastEmit_f:
/// FastEmit_f - This method is called by target-independent code
  /// to request that an instruction with the given type, opcode, and
  /// floating-point immediate operand be emitted.
  virtual unsigned FastEmit_f(MVT VT,
                              MVT RetVT,
                              unsigned Opcode,
                              const ConstantFP *FPImm);

Currently, it emits an accidentally overloaded version without the const on the
ConstantFP*. This doesn't affect anything in the tree, since nothing causes that
method to be autogenerated, but I have been playing with some ARM TableGen
refactorings that hit this problem.
