eea7fd1c3e MC/ARM: Use aggressive symbol folding (important for jump tables, for example).

1f9fd0b79b MC/Expr: Implemnt more aggressive folding during symbol evaluation using 
IsSymbolRefDifferenceFullyResolved(). For example, we will now fold away
something like:
--
_a:
...
L0:
...
L1:
...
.long (L1 - L0) / 2
--

6979fc1057 MC/Mach-O: On second thought, use a custom hook for enabling aggressive 
IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on
enough cases for x86-32 that I would rather wait a bit on it.
 - In practice, we will want to change this eventually because it only means we
   generate less relocations (it also eliminates the need for the horrible
   '.set' hack that Darwin requires in some places).

14208868a4 MC/Mach-O: Implement IsSymbolRefDifferenceFullyResolved. 
- Unlike for fixups, we always do the "reliable" thing (not just for x86_64).
 - Since Darwin 'as' would typically reject things that using this will allow,
   we don't need to worry about compatibility.

40f23cd5ca Provide LiveIntervalUnion::Query::checkLoopInterference. 
This is a three-way interval list intersection between a virtual register, a
live interval union, and a loop. It will be used to identify interference-free
loops for live range splitting.

f8949c3d1a Revert r64460. strtol and friends cannot be marked readonly, even with 
a null endptr argument, because they may write to errno.

This fixes a seflhost miscompile observed on Linux targets when TBAA
was enabled.

56dc4fc838 Fix a bug in the loop in JumpThreading::ProcessThreadableEdges() where it could falsely produce a MultipleDestSentinel value if the first predecessor ended with an 'indirectbr'. If that happened, it caused an unnecessary FindMostPopularDest() call. 
This wasn't a correctness problem, but it broke the fast path for single-predecessor blocks.

22de496ae3 Speculatively revert commit 121905 since it looks like it might have broken the 
dragonegg self-host buildbot.  Original commit message:

Add an InstCombine transform to recognize instances of manual overflow-safe addition
(performing the addition in a wider type and explicitly checking for overflow), and
fold them down to intrinsics.  This currently only supports signed-addition, but could
be generalized if someone works out the magic constant formulas for other operations.
