FIX for PR1799: When a load is unfolded from an instruction, check if it is a new node. If not, do not create a new SUnit.

how to lower them (with no attempt made to be
efficient, since they should only occur for
unoptimized code).

Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

Remove ugly and horrible code.  It's not necessary for correctness, and can be added back later if it causes code quality issues.

Implicit def instructions, e.g. X86::IMPLICIT_DEF_GR32, are always re-materializable and they should not be spilled.

SelectionDAG::getConstant, in the same way as vector floating-point
constants. This allows the legalize expansion code for @llvm.ctpop and
friends to be usable with vector types.

If deleting a reload instruction due to reuse (value is available in register R and reload is targeting R), make sure to invalidate the kill information of the last kill.

Also, simplify the check for a BB in a sub loop.

CollectorMetadata, so the latter may be subclassed.
