Don't pull vector sext through both hands of a logical operation, since doing so prevents the fusion of vector sext and setcc into vsetcc.
Add a testcase for the above transformation.
Fix a bogus use of APInt noticed while tracking this down.

undef and the shuffle mask is adjusted to only reference elements from the 1st
operand.  Radar 7434842.

The MO reference to a MachineOperand can be invalidated by
MachineInstr::addOperand. Don't even use it for debugging.

Emit method definition DIE at module level (even for methods with inlined functino body at soure level) so that the debugger can invoke it. This fixes many test failures in gdb test suite.

that it doesn't have dangling pointers when abstract types are resolved. This
modifies it somewhat to address comments: making the "StructLayoutMap" an
anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
adding asserts where helpful.

- A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
- If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
- Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".
