Dale Johannesen 6f7d5b22bb Emit correct code when making a ConstantPool entry for a vector 
constant whose component type is not a legal type for the target.
(If the target ConstantPool cannot handle this type either, it has
an opportunity to merge elements.  In practice any target with
8-bit bytes must support i8 *as data*).  7320806 (partial).

Jakob Stoklund Olesen 4453dc976b Teach PHIElimination to split critical edges when -split-phi-edges is enabled. 
Critical edges leading to a PHI node are split when the PHI source variable is
live out from the predecessor block. This help the coalescer eliminate more
PHI joins.

Jeffrey Yasskin b40d3f76a0 Fix DenseMap iterator constness. 
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

Patch by Victor Zverovich!

Dan Gohman 2745d19287 Print "..." instead of all the uninteresting register clobbers on call 
instructions. This makes CodeGen dumps significantly less noisy.

Evan Cheng 7ff831962a - Add TargetInstrInfo::isIdentical(). It's similar to MachineInstr::isIdentical 
except it doesn't care if the definitions' virtual registers differ. This is
  used by machine LICM and other MI passes to perform CSE.
- Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical.
  Since pc relative constantpool entries are always different, this requires it
  it check if the values can actually the same.

Jakob Stoklund Olesen 4141d8ee92 Fix inverted conflict test in -early-coalesce. 
A non-identity copy cannot be coalesced when the phi join destination register
is live at the copy site.

Also verify the condition that the PHI join source register is only used in
the PHI join. Otherwise the coalescing is invalid.
