The rationale is to get YAML filenames in diagnostics from
yaml::Stream::printError -- currently the filename is hard-coded as
"YAML" because there's no buffer information available.

It turned out that ARM wants different layout of type infos.
This is yet another patch in attempt to fix PR7187

This patch moves the isInlineViable function from the InlineAlways pass into
the InlineCostAnalyzer and then changes the InlineCost computation to use that
simple check for always-inline functions. All the special-case checks for
AlwaysInline in the CallAnalyzer can then go away.

operands of the expression being written was wrongly thought to be reusable as
an inner node of the expression resulting in it turning up as both an inner node
*and* a leaf, creating a cycle in the def-use graph. This would have caused the
verifier to blow up if things had gotten that far, however it managed to provoke
an infinite loop first.

On PPC the stack pointer is X1, but ADJCALLSTACK writes R1.

This is a partial solution to PR14351. It removes some of the special
significance of the first incoming phi value in the phi aliasing checking logic
in BasicAA. In the context of a loop, the old logic assumes that the first
incoming value is the interesting one (meaning that it is the one that comes
from outside the loop), but this is often not the case. With this change, we
now test first the incoming value that comes from a block other than the parent
of the phi being tested.

This patch replaces the hard coded GPR pair [R0, R1] of
Intrinsic:arm_ldrexd and [R2, R3] of Intrinsic:arm_strexd with
even/odd GPRPair reg class.
Similar to the lowering of atomic_64 operation.

Before, the parser would assert on the following code:
@a2 = global i8 addrspace(1)* @a
@a = addrspace(1) global i8 0
because the type of @a was "i8*" instead of "i8 addrspace(1)*" when parsing
the initializer for @a2.

replaced by this patch is equivalent to the new logic, but you'd be wrong, and
that's exactly where the bug was. There's a similar bug in instsimplify which
manifests itself as instsimplify failing to simplify this, rather than doing it
wrong, see next commit.

all symbols during object loading, not just global ones.
This fixes JIT execution of code using llvm.global_ctors with internal
linkage constructors.

It turns out that the operands of a Constant are not always themselves
Constant. For example, one of the operands of BlockAddress is
BasicBlock, which is not a Constant.
This should fix the dragonegg-x86_64-linux-gcc-4.6-test build which
broke in r168037.
