Since Eric's r123367 commit, the default stack alignment for x86 32-bit
has changed to be 16-bytes. Since then, the MaxStackAlignmentHeuristicPass
hasn't been really used, but with AVX it becomes useful again, since per
ABI compliance we don't always align the stack to 256-bit, but only when
there are 256-bit incoming arguments.
ReserveFP was only used by this pass, but there's no RA target hook that
uses getReserveFP() to check for the presence of FP (since nothing was
triggering the pass to run, the uses of getReserveFP() were removed
through time without being noticed). Change this pass to use
setForceFramePointer, which is properly called by MachineFunction
hasFP method.
The testcase is very big and dependent on RA, not sure if it's worth
adding to test/CodeGen/X86.

Spill mode: Hoist back-copies locally.
...
The leaveIntvAfter() function normally inserts a back-copy after the
requested instruction, making the back-copy kill the live range.
In spill mode, try to insert the back-copy before the last use instead.
That means the last use becomes the kill instead of the back-copy. This
lowers the register pressure because the last use can now redefine the
same register it was reading.
This will also improve compile time: The back-copy isn't a kill, so
hoisting it in hoistCopiesForSize() won't force a recomputation of the
source live range. Similarly, if the back-copy isn't hoisted by the
splitter, the spiller will not attempt hoisting it locally.

Disable local spill hoisting for non-killing copies.
...
If the source register is live after the copy being spilled, there is no
point to hoisting it. Hoisting inside a basic block only serves to
resolve interferences by shortening the live range of the source.

If we see an EOF w/o a preceding end-of-line, return an EndOfStatement
token before returning the Eof token.

Trace through sibling PHIs in bulk.
...
When traceSiblingValue() encounters a PHI-def value created by live
range splitting, don't look at all the predecessor blocks. That can be
very expensive in a complicated CFG.
Instead, consider that all the non-PHI defs jointly dominate all the
PHI-defs. Tracing directly to all the non-PHI defs is much faster that
zipping around in the CFG when there are many PHIs with many
predecessors.
This significantly improves compile time for indirectbr interpreters.

Use getPrevSlot() instead of getPrevIndex().
...
The getPrevIndex() function moves to the same slot in the previous
instruction. For getVNInfoBefore(), we just need the previous slot in
the same instruction.

Speed up LiveIntervals::shrinkToUse with some caching.
...
Blocks with multiple PHI successors only need to go on the worklist
once. Use a SmallPtrSet to track the live-out blocks that have already
been handled. This is a lot faster than the two live range check we
would otherwise do.
Also stop recomputing hasPHIKill flags. Like RenumberValues(), it is
conservatively correct to leave them in, and they are not used for
anything important.

Revert r139782, "RemoveCopyByCommutingDef doesn't need hasPHIKill()."

It does, after all.
RemoveCopyByCommutingDef rewrites the uses of one particular value
number in A. It doesn't know how to rewrite phi uses, so there can't be
any.

Stop verifying hasPHIKill() flags.

There is only one legitimate use remaining, in addIntervalsForSpills().
All other calls to hasPHIKill() are only used to update PHIKill flags.
The addIntervalsForSpills() function is part of the old spilling
framework, only used by linearscan.

RemoveCopyByCommutingDef doesn't need hasPHIKill().
...
Instead, let HasOtherReachingDefs() test for defs in B that overlap any
phi-defs in A as well. This test is slightly different, but almost
identical.
A perfectly precise test would only check those phi-defs in A that are
reachable from AValNo.

It is safe to remat a value killed by phis.
...
The source live range is recomputed using shrinkToUses() which does
handle phis correctly. The hasPHIKill() condition was relevant in the
old days when ReMaterializeTrivialDef() tried to recompute the live
range itself.
The shrinkToUses() function will mark the original def as dead when no
more uses and phi kills remain. It is then removed by
runOnMachineFunction().

Leave hasPHIKill flags alone in LiveInterval::RenumberValues.
...
It is conservatively correct to keep the hasPHIKill flags, even after
deleting PHI-defs.
The calculation can be very expensive after taildup has created a
quadratic number of indirectbr edges in the CFG, and the hasPHIKill flag
isn't used for anything after RenumberValues().
