Fix nested CrashRecoveryContexts with LLVM_ENABLE_THREADS=OFF, allow them.

libclang uses a CrashRecoveryContext, and building a module does too. If a
module gets built through libclang, nested CrashRecoveryContexts are used.  They
work fine with threads as things are stored in ThreadLocal variables, but in
LLVM_ENABLE_THREADS=OFF builds the two recovery contexts would write to the
same globals.

To fix, keep active CrashRecoveryContextImpls in a list and have the global
point to the innermost one, and do something similar for
tlIsRecoveringFromCrash.

Fix possible infinite loop in shrink wrapping when searching for save/restore
points.

There is an infinite loop that can occur in Shrink Wrapping while searching
for the Save/Restore points.

Part of this search checks whether the save/restore points are located in
different loop nests and if so, uses the (post) dominator trees to find the
immediate (post) dominator blocks. However, if the current block does not have
any immediate (post) dominators then this search will result in an infinite
loop. This can occur in code containing an infinite loop.

The modification checks whether the immediate (post) dominator is different from
the current save/restore block. If it is not, then the search terminates and the
current location is not considered as a valid save/restore point for shrink wrapping.

Kit Barton [Thu, 6 Aug 2015 18:02:53 +0000 (18:02 +0000)]
This patch changes the interface to enable the shrink wrapping optimization.

It adds a new constructor, which takes a std::function predicate function that
is run at the beginning of shrink wrapping to determine whether the optimization
should run on the given machine function. The std::function can be overridden by
each target, allowing target-specific decisions to be made on each machine
function.

This is necessary for PowerPC, as the decision to run shrink wrapping is
partially based on the ABI. Futhermore, this operates nicely with the GCC iFunc
capability, which allows option overrides on a per-function basis.

Rotate the algorithm for remapping distinct nodes in order to simplify
how uniquing cycles get resolved.  This removes some of the recursion,
and, most importantly, exposes all uniquing cycles at the top-level.
Besides being a little more efficient -- temporary MDNodes won't live as
long -- the clearer logic should help protect against bugs like those
fixed in r243961 and r243976.

What are uniquing cycles?  Why do they present challenges when remapping
metadata?

    !0 = !{!1}
    !1 = !{!0}

!0 and !1 form a simple uniquing cycle.  When remapping from one
metadata graph to another, every uniquing cycle gets "duplicated"
through a dance:

    !0-temp = !{!1?}     ; map(!0): clone !0, VM[!0] = !0-temp
    !1-temp = !{!0?}     ; ..map(!1): clone !1, VM[!1] = !1-temp
    !1-temp = !{!0-temp} ; ..map(!1): remap !1's operands
    !2      = !{!0-temp} ; ..map(!1): uniquify: !1-temp => !2
    !0-temp = !{!2}      ; map(!0): remap !0's operands
    !3      = !{!2}      ; map(!0): uniquify: !0-temp => !3

    ; Result
    !2 = !{!3}
    !3 = !{!2}

(In the two "uniquify" steps above, the operands of !X-temp are compared
to the operands of !X.  If they're the same, then !X-temp gets RAUW'ed
to !X; if they're different, then !X-temp is promoted to a new unique
node.  The latter case always hits in for uniquing cycles, so we
duplicate all the nodes involved.)

Why is this a problem?  Uniquable Metadata nodes that have temporary
node as transitive operands keep RAUW support until the temporary nodes
get finalized.  With non-cycles, this happens automatically: when a
uniquable node's count of unresolved operands drops to zero, it
immediately sheds its own RAUW support (possibly triggering the same in
any node that references it).  However, uniquing cycles create a
reference cycle, and uniqued nodes that transitively reference a
uniquing cycle are "stuck" in an unresolved state until someone calls
`MDNode::resolveCycles()` on a node in the unresolved subgraph.

Distinct nodes should help here (and mostly do): since they aren't
uniqued anywhere, they are guaranteed not to be RAUW'ed.  They
effectively form a barrier between uniqued nodes, breaking some uniquing
cycles, and shielding uniqued nodes from uniquing cycles.

Unfortunately, with this barrier in place, the unresolved subgraph(s)
can be disjoint from the top-level node.  The mapping algorithm needs to
find at least one representative from each disjoint subgraph.  But which
nodes are *stuck*, and which will get resolved automatically?  And which
nodes are in the unresolved subgraph?  The old logic was conservative.

This commit rotates the logic for distinct nodes, so that we have access
to unresolved nodes at the top-level call to `llvm::MapMetadata()`.
Each time we return to the top-level, we know that all temporaries have
been RAUW'ed away.  Here, it's safe (and necessary) to call
`resolveCycles()` immediately on unresolved operands.

This should also perform better than the old algorithm.  The recursion
stack is shorter, temporary nodes don't live as long, and there are
fewer tracking references to unresolved nodes.  As the debug info graph
introduces more 'distinct' nodes, remapping should incrementally get
cheaper and cheaper.

Aside from possible performance improvements (and reduced cruft in the
`LLVMContext`), there should be no functionality change here.

[TTI] Make the cost APIs in TargetTransformInfo consistently use 'int'
rather than 'unsigned' for their costs.

For something like costs in particular there is a natural "negative"
value, that of savings or saved cost. As a consequence, there is a lot
of code that subtracts or creates negative values based on cost, all of
which is prone to awkwardness or bugs when dealing with an unsigned
type. Similarly, we *never* want these values to wrap, as that would
cause Very Bad code generation (likely percieved as an infinite loop as
we try to emit over 2^32 instructions or some such insanity).

All around 'int' seems a much better fit for these basic metrics. I've
added asserts to ensure that at least the TTI interface never returns
negative numbers here. If we ever have a use case for negative numbers,
we can remove this, but this way a bug where someone used '-1' to
produce a 'very large' cost will be caught by the assert.

This passes all tests, and is also UBSan clean.

No functional change intended.

the requirement. This is done with a (very small) recursion through PHIs

This moves the iterator to TerminatorInst as thats what we're actually
