6ed9284c2b Compute correct frame sizes for SPARC v9 64-bit frames.
The save area is twice as big and there is no struct return slot. The
stack pointer is always 16-byte aligned (after adding the bias).

Also eliminate the stack adjustment instructions around calls when the
function has a reserved stack frame.

b3d25a940c Fix PointerIntPair to be enum class compatible.
Some parts of PointerIntPair assumed that the IntType of the pair was implicitly
convertible to intptr_t, which is not the case for enum class values. Add a
static_cast<intptr_t> to make these conversions explicit and allow
PointerIntPair to be used with an enum class IntType. While we're here, rename
some of the argument values so we don't have variables named "Int" floating
around.

4fd00c55d0 Redo the fix Benjamin Kramer committed in r178793 about iterator invalidation in Reassociate.
I brazenly think this change is slightly simpler than r178793 because: 
  - no "state" in functor
  - "OpndPtrs[i]" looks simpler than "&Opnds[OpndIndices[i]]" 

  While I can reproduce the probelm in Valgrind, it is rather difficult to come up
a standalone testing case. The reason is that when an iterator is invalidated,
the stale invalidated elements are not yet clobbered by nonsense data, so the
optimizer can still proceed successfully. 

  Thank Benjamin for fixing this bug and generously providing the test case.

813456527e X86 cost model: Model cost for uitofp and sitofp on SSE2
The costs are overfitted so that I can still use the legalization factor.

For example the following kernel has about half the throughput vectorized than
unvectorized when compiled with SSE2. Before this patch we would vectorize it.

unsigned short A[1024];
double B[1024];
void f() {
  int i;
  for (i = 0; i < 1024; ++i) {
    B[i] = (double) A[i];
  }
}

5ee67e8e76 Generate PPC early conditional returns
PowerPC has a conditional branch to the link register (return) instruction: BCLR.
This should be used any time when we'd otherwise have a conditional branch to a
return. This adds a small pass, PPCEarlyReturn, which runs just prior to the
branch selection pass (and, importantly, after block placement) to generate
these conditional returns when possible. It will also eliminate unconditional
branches to returns (these happen rarely; most of the time these have already
been tail duplicated by the time PPCEarlyReturn is invoked). This is a nice
optimization for small functions that do not maintain a stack frame.

bcff69a1e0 Don't define our own global 'endl' variable. While technically it had
internal linkage and so wasn't a patent bug, it doesn't make any sense
here. We can avoid even calling operator<< by just embedding the newline
in the string literals that were already being streamed out. It also
gives the impression of some line-ending agnosticisms which is not
present, and that flushing happens when it doesn't.

If we want to use std::endl, we could do that, but honestly it doesn't
seem remotely worth it. Using '\n' directly is much more clear when
working with raw_ostream.

It also happens to fix builds with old crufty GCC STL implementations
that include std::endl into the global namespace (or headers written to
be compatible with such atrocities).

59889f7f49 Cleanup and improve PPC fsel generation
First, we should not cheat: fsel-based lowering of select_cc is a
finite-math-only optimization (the ISA manual, section F.3 of v2.06, makes
this clear, as does a note in our own README).

This also adds fsel-based lowering of EQ and NE condition codes. As it turned
out, fsel generation was covered by a grand total of zero regression test
cases. I've added some test cases to cover the existing behavior (which is now
finite-math only), as well as the new EQ cases.

cd3d60c450 TargetLowering: Fix getTypeConversion handling of extended vector types
The code in getTypeConversion attempts to promote the element vector type
before it trys to split or widen the vector.
After it failed finding a legal vector type by promoting it would continue using
the promoted vector element type. Thereby missing legal splitted vector types.
For example the type v32i32 that has a legal split of 4 x v3i32 on x86/sse2
would be transformed to: v32i256 and from there on successively split to:
v16i256, v8i256, v1i256 and then finally ends up as an i64 type.
By resetting the vector element type to the original vector element type that
existed before the promotion the code will attempt to split the vector type to
smaller vector widths of the same type.
