This commit updates the link components in the Makefile.

helper function. This leaves both trivial cases handled entirely in
helper functions and merely manages the list of allocas to process in
the run method.
The next step will be to handle all of the trivial promotion work prior
to even creating the core class and the subsequent simplifications that
enables.

a single block into the helper routine. This takes advantage of the fact
that we can directly replace uses prior to any store with undef to
simplify matters and unconditionally promote allocas only used within
one block.
I've removed the special handling for the case of no stores existing.
This has no semantic effect but might slow things down. I'll fix that in
a later patch when I refactor this entire thing to be easier to manage
the different cases.

handles the general cases.
The hope is to refactor this so that we don't end up building the entire
class for the trivial cases. I also want to lift a lot of the early
pre-processing in the initial segment of run() into a separate routine,
and really none of it needs to happen inside the primary promotion
class.
These routines in particular used none of the actual state in the
promotion class, so they don't really make sense as members.

This struct is nicely independent of everything else, and we already
needed a foward declaration here. It's simpler to just define it
immediately.

GlobalOpt simplifies llvm.compiler.used by removing any members that are also
in the more strict llvm.used. Handle the special case where llvm.compiler.used
becomes empty.

Simplify DIxxx:Verify to not call Verify on an operand. Instead, we use
DebugInfoFinder to list all MDNodes that should be a DIScope and all MDNodes
that should be a DIType and we will call Verify on those lists.

indirect branches correctly. Under some circumstances, this led to the deletion
of basic blocks that were the destination of indirect branches. In that case it
left indirect branches to nowhere in the code.
This patch replaces, and is more general than either of the previous fixes for
indirect-branch-analysis issues, r181161 and r186461.
For other branches (not indirect) this refactor should have *almost* identical
behavior to the previous version. There are some corner cases where this
refactor is able to analyze blocks that the previous version could not (e.g.
this necessitated the update to thumb2-ifcvt2.ll).

The original change was rolled back in r186627 because of test
failures on the big endian machine. I believe I fixed the issue
so re-submitting.

We were incorrectly using compiler_used instead of compiler.used. Unfortunately
the passes using the broken name had tests also using the broken name.

The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.
We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.

The insn definitions themselves crept into r186689, sorry.
This should be the last of the distinct-ops instructions.

Follows the same lines as r186686, but much more limited, since we only
use ADD LOGICAL for multi-i64 additions.

The atomic tests assume the two-operand forms, so I've restricted them to z10.
Running and-01.ll, or-01.ll and xor-01.ll for z196 as well as z10 shows why
using convertToThreeAddress() is better than exposing the three-operand forms
first and then converting back to two operands where possible (which is what
I'd originally tried). Using the three-operand form first stops us from
taking advantage of NG, OG and XG for spills.

This first step just adds definitions for SLLK, SRLK and SRAK.
The next patch will actually make use of them during codegen.
insn-bad.s tests that some form of error is reported when using these
instructions on z10. More work is needed to get the "instruction requires:
distinct-ops" that we'd ideally like, so I've stubbed that part out for now.
I'll come back and make it mandatory once the necessary changes are in.
