[CMake] Flag recursive cmake invocations for cross-compile

Summary:
Cross-compilation uses recursive cmake invocations to build native host
tools.  These recursive invocations only forward a fixed set of
variables/options, since the native environment is generally the default.
This change adds -DLLVM_TARGET_IS_CROSSCOMPILE_HOST=TRUE to the recursive
cmake invocations, so that cmake files can distinguish these recursive
invocations from top-level ones, which can explain why expected options
are unset.

LLILC will use this to avoid trying to generate its build rules in the
crosscompile native host target (where it is not needed), which would fail
if attempted because LLILC requires a cmake variable passed on the command
line, which is not forwarded in the recursive invocation.

Fix vector splitting for extract_vector_elt and vector elements of <8-bits.

Summary:
One of the vector splitting paths for extract_vector_elt tries to lower:
    define i1 @via_stack_bug(i8 signext %idx) {
      %1 = extractelement <2 x i1> <i1 false, i1 true>, i8 %idx
      ret i1 %1
    }
to:
    define i1 @via_stack_bug(i8 signext %idx) {
      %base = alloca <2 x i1>
      store <2 x i1> <i1 false, i1 true>, <2 x i1>* %base
      %2 = getelementptr <2 x i1>, <2 x i1>* %base, i32 %idx
      %3 = load i1, i1* %2
      ret i1 %3
    }
However, the elements of <2 x i1> are not byte-addressible. The result of this
is that the getelementptr expands to '%base + %idx * (1 / 8)' which simplifies
to '%base + %idx * 0', and then simply '%base' causing all values of %idx to
extract element zero.

This commit fixes this by promoting the vector elements of <8-bits to i8 before
splitting the vector.

This fixes a number of test failures in pocl.

32-bit funclets have short prologues that allocate enough stack for the
largest call in the whole function. The runtime saves CSRs for the
funclet. It doesn't restore CSRs after we finally transfer control back

32-bit funclets also have to adjust the incoming EBP value, which is
what llvm.x86.seh.recoverframe does in the old model.

64-bit funclets need to spill CSRs as normal. For simplicity, this just
spills the same set of CSRs as the parent function, rather than trying
to compute different CSR sets for the parent function and each funclet.

contain either functions or global variables. A function bitset is lowered to
a jump table that is laid out before one of the functions in the bitset.

[SelectionDAG] Swap commutative binops before constant-based folding

r246937 (that SDAG simplification can lead to us generating an ISD::OR node
with a constant zero LHS), I ran across this:

We generically canonicalize commutative binary-operation nodes in SDAG getNode
so that, if only one operand is a constant, it will be on the RHS.  However, we
were doing this only after a bunch of constant-based simplification checks that
all assume this canonical form (that any constant will be on the RHS). Moving
the operand-swapping canonicalization prior to these checks seems like the
right thing to do (and, as it turns out, causes SDAG to completely fold away the
computation in test/CodeGen/ARM/2012-11-14-subs_carry.ll, just like InstCombine
would do).
