Also add a check for llvm.used in the verifier and simplify clients now that
they can assume they have a ConstantArray.

This reverts commit r179840 with a fix to test/DebugInfo/two-cus-from-same-file.ll
I'm not sure why that test only failed on ARM & MIPS and not X86 Linux, even
though the debug info was clearly invalid on all of them, but this ought to fix
it.

I think it's almost impossible to fold atomic fences profitably under
LLVM/C++11 semantics. As a result, this is now unused and just
cluttering up the target interface.

trying to move as much FastISel logic as possible out of the main path in
SelectionDAGISel - intermixing them just adds confusion.

Adding another CU-wide list, in this case of imported_modules (since they
should be relatively rare, it seemed better to add a list where each element
had a "context" value, rather than add a (usually empty) list to every scope).
This takes care of DW_TAG_imported_module, but to fully address PR14606 we'll
need to expand this to cover DW_TAG_imported_declaration too.

When the SlotIndexes pass was introduced it was intended to support insertion
of code during register allocation. Removal of code was a minor consideration
(and raised the question of what to do about dangling SlotIndex objects pointing
to the erased index), so I opted to keep all indexes around indefinitely and
simply null out those that weren't being used.
Nowadays people are moving more code around (e.g. via HandleMove), which means
more zombie indexes. I want to start killing off indexes when we're done with
them to reclaim the resources they use up.

Semantics of parameters named Index and Idx were inconsistent between
"include/llvm/IR/Attributes.h", "lib/IR/AttributeImpl.h" and
"lib/IR/Attributes.cpp": sometimes these were fixed 1-based indexes of IR
parameters (or AttributeSet::ReturnIndex for IR return values or
AttributeSet::FunctionIndex for IR functions), other times they were the
internal slot for storage in the underlying AttributeSetImpl. I renamed usage of
the former to "Index" and usage of the latter to "Slot" ("Slot" was already
being used consistently for the latter in a subset of cases)

1. Verify::VerifyParameterAttrs in "lib/IR/Verifier.cpp" and
AttrBuilder::removeFunctionOnlyAttrs in "lib/IR/Attributes.cpp" (only called
by Verify::VerifyFunctionAttrs) separately maintained a list of function-only
attribute types. I've consolidated the logic into a new function used for
both cases in "lib/IR/Verifier.cpp", so this logic is in one place (other
than the AsmParser front-end)
2. Various functions in "lib/IR/Verifier.cpp" passed AttributeSet around by
reference needlessly, as it's just a handle to an immutable pimpl body.

It's sometimes beneficial to emit a testcase with the old style attribute
syntax. Allow someone to do this.

* We only ever specialize these templates with an instantiation of ELFType,
so we don't need a template template.
* Replace LLVM_ELF_COMMA with just passing the individual parameters to the
macro. This requires a second macro for when we only have ELFT, but that
is still a small win.

I will remove the isBigEndianHost function once I update clang.
The ifdef logic is designed to
* not use configure/cmake to avoid breaking -arch i686 -arch ppc.
* default to little endian
* be as small as possible
It looks like sys/endian.h is the preferred header on most modern BSD systems,
but it is better to change this in a followup patch as machine/endian.h is
available on FreeBSD, OpenBSD, NetBSD and OS X.
