3a02cbcd03 Refactor rewriting for PHI nodes into a separate function.

0a145f3d90 First step in eliminating the CarryDefIsUnused and CarryDefIsUsed predicates. 
They won't work with the new ISel mechanism, as Requires predicates are no
longer allowed to reference the node being selected. Moving the predicate to
the patterns instead solves the problem.

This patch handles ARM mode. Thumb2 will follow.

1665b0a224 Fix pr6111: Avoid using the LR register for the target address of an indirect 
branch in ARM v4 code, since it gets clobbered by the return address before
it is used.  Instead of adding a new register class containing all the GPRs
except LR, just use the existing tGPR class.

c2385a0741 Split the main for-each-use loop again, this time for GenerateTruncates, 
as it also peeks at which registers are being used by other uses. This
makes LSR less sensitive to use-list order.

ac8a3d0b5b It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

014bf215c3 Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

50922bbe74 When testing whether a given SCEV depends on a temporary symbolic 
name, test whether the SCEV itself is that temporary symbolic name,
in addition to checking whether the symbolic name appears as a
possibly-indirect operand.

ce947366ec When complicated expressions are broken down into subexpressions 
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.

1d826a76f5 In rememberInstruction, if the value being remembered is the

regression test.

98d5c3141e Split some code out to a helper function (FindReusablePredBB) 
and add a doxygen comment.

Cache the phi entry to avoid doing tons of 
PHINode::getBasicBlockIndex calls in the common case.

On my insane testcase from re2c, this speeds up CGP from
617.4s to 7.9s (78x).

277cccc58f PHINode::getBasicBlockIndex is O(n) in the number of inputs

d135f14f61 Fix PR6283. 
When coalescing with a physreg, remember to add imp-def and imp-kill when
dealing with sub-registers.

Also fix a related bug in VirtRegRewriter where substitutePhysReg may
reallocate the operand list on an instruction and invalidate the reg_iterator.
This can happen when a register is mentioned twice on the same instruction.
