handles for the old value when doing RAUW. Barf if it occurs, since it is almost

The isLoadFromStackSlot and isStoreToStackSlot have no way of reporting

subregister operands like this:
%reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8)
Make them return false when subreg operands are present. VirtRegRewriter is
making bad assumptions otherwise.

It's better to have the arrays, which would trigger the creation of stack
...
protectors, to be near the stack protectors on the stack. Accomplish this by
tagging the stack object with a predicate that indicates that it would trigger
this. In the prolog-epilog inserter, assign these objects to the stack after the
stack protector but before the other objects.

Temporary hack to let codegen assert or generate poor code in case

we are using AVX and no AVX version of the desired intruction is present,
this is better for incremental dev (without fallbacks it's easier to spot
what's missing). Not sure this is the best hack thought (we can also disable
all HasSSE* predicates by dinamically marking them 'false' if AVX is present)

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
...
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.
This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.
