Teach MachineBasicBlock::updateTerminator() to handle a failing TII->ReverseBranchCondition(Cond) call.

This fixes the MallocBench/cfrac test case regression.

The hasNoModRefInfoForCalls isn't worth it as a filter because 
basicaa provides m/r info and everything chains to it, so remove
it.

values, resolving references to them, and then removing the definitions.
If a template argument is set to an undefined value, we need to resolve
references to that argument to an explicit undefined value.  The current code
leaves the reference to the template argument as it is, which causes an
assertion failure later when the definition of the template argument is
removed.

Minor optimization: when doing eq/ne comparions and RHS is a constant - swap operands, this will allow us to fold imm into comparison.

Add predicate operand to NEON instructions. Fix lots (but not all) 80 col violations in ARMInstrNEON.td.

When splitting a critical edge, the registers live through the edge are:

- Used in a PHI instruction, or
- Live out from the predecessor, and
- Live in to the successor.

This allows the coalescer to eliminate even more phi joins.

DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.
