implementations with a new MachineInstr::isInvariantLoad, which uses
MachineMemOperands and is target-independent. This brings MachineLICM
and other functionality to targets which previously lacked an
isInvariantLoad implementation.

This is just to be more consistent with the forthcoming code for vld3/4.

its definition may be defined, including in a class.

Also, put in an assertion when trying to instantiate a class template
partial specialization of a member template, which is not yet
implemented.

a virtual register to eliminate a frame index, it can return that register
and the constant stored there to PEI to track. When scavenging to allocate
for those registers, PEI then tracks the last-used register and value, and
if it is still available and matches the value for the next index, reuses
the existing value rather and removes the re-materialization instructions.
Fancier tracking and adjustment of scavenger allocations to keep more
values live for longer is possible, but not yet implemented and would likely
be better done via a different, less special-purpose, approach to the
problem.

eliminateFrameIndex() is modified so the target implementations can return
the registers they wish to be tracked for reuse.

ARM Thumb1 implements and utilizes the new mechanism. All other targets are
simply modified to adjust for the changed eliminateFrameIndex() prototype.

It does NOT update the value if the key is already in the map,
it also returns false if the key is already in the map, regardless
if the value matched.

Add 'template' keyword to disambiguate the use of a member template within a templated class.  Hopefully this will please the buildbots.

Add a MangleContext and pass it to all mangle functions. It will be used for keeping state, such as identifiers assigned to anonymous structs as well as scope encoding.

Change ExplodedNode to have its NodeGroups all BumpPtrAllocated, avoiding malloc() traffic when adding successors/predecessors to a node.  This was done by introducing BumpVector, which is essentially SmallVector with all memory being BumpPtrAllocated (this can certainly be cleaned up or moved into llvm/ADT).

This change yields a 1.8% speed increase when running the analyzer (with -analyzer-store=region) on a small benchmark file.

When MallocInst goes away this code will be subsumed as part of

Doug, please review. There is a FIXME in the test case with a question

before set of builtins are added to the candidate list).
