0c0a3effde Convert -indvars tests that rely on SCEV expansion to -loop-reduce tests.

3e29671cca Revert a series of commits to MCJIT to get the build working in CMake
(and hopefully on Windows). The bots have been down most of the day
because of this, and it's not clear to me what all will be required to
fix it.

The commits started with r153205, then r153207, r153208, and r153221.
The first commit seems to be the real culprit, but I couldn't revert
a smaller number of patches.

When resubmitting, r153207 and r153208 should be folded into r153205,
they were simple build fixes.

544b9b426f [fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271%
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise 
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.

0191bfcf7a Add a ${pathsep} variable to lit that expands to : (or ; on win32).
This is in braces so that it doesn't conflict with the existing %p.
It uses braces instead of parens because parens would have to be

331ff3b1d1 Checking a build_vector for an all-ones value.
Type legalization can zero-extend the elements of the build_vector node, so,
for example, we may have an <8 x i8> with i32 elements of value 255. That
should return 'true' for the vector being all ones.

ff739c1575 Teach instsimplify to gracefully degrade in the presence of instructions
not attched to a basic block or function. There are conservatively
correct answers in these cases, and this makes the analysis more useful
in contexts where we have a partially formed bit of IR.

I don't have any way to test this directly... suggestions welcome here,
but I'm not seeing anything sadly. I only found this using a subsequent
patch to the inliner which runs instsimplify on partially inlined
instructions, and even then only on a quite large program. I never got
a reasonable testcase out of it, and anything I do get is likely to be
quite fragile due to requiring an interaction of two different passes,
and the only result being a segfault if it goes wrong.

6244b51888 Organize LLVM C API docs into doxygen modules; add docs
This gives a lot of love to the docs for the C API. Like Clang's
documentation, the C API is now organized into a Doxygen "module"
(LLVMC). Each C header file is a child of the main module. Some modules
(like Core) have a hierarchy of there own. The produced documentation is
thus better organized (before everything was in one monolithic list).

This patch also includes a lot of new documentation for APIs in Core.h.
It doesn't document them all, but is better than none. Function docs are
missing @param and @return annotation, but the documentation body now
commonly provides help details (like the expected llvm::Value sub-type
to expect).

4211c196d4 Make sure ImmutableSet never inserts Tombstone/Entry into DenseMap.
ImmutAVLTree uses random unsigned values as keys into a DenseMap,
which could possibly happen to be the same value as the Tombstone or
Entry keys in the DenseMap.

Test case is hard to come up with. We randomly get failures on the
internal static analyzer bot, which most likely hits this issue
(hard to be 100% sure without the full stack).

5069b21b45 RuntimeDyldMachO has the ability to keep track of
relocations (i.e., pieces of data whose addresses
are referred to elsewhere in the binary image) and
update the references when the section containing
the relocations moves.  The way this works is that
there is a map from section IDs to lists of
relocations.

Because the relocations are associated with the
section containing the data being referred to, they
are updated only when the target moves.  However,
many data references are relative and also depend
on the location of the referrer.

To solve this problem, I introduced a new data
structure, Referrer, which simply contains the
section being referred to and the index of the
relocation in that section.  These referrers are
associated with the source containing the
reference that needs to be updated, so now
regardless of which end of the relocation moves,
the relocation will now be updated correctly.
