with modules that are imported after we have already searched in the
global method pool for a given selector. For PCH, it's a slight
pessimization to be fixed soon.

to Sema so that Sema can unique them, which keeps the chains shorter.

This is accomplished by periodically reclaiming nodes in the graph.  This was an optimization
done before the CFG was linearized, but the CFG linearization destroyed that optimization since each
freshly created node couldn't be reclaimed and we only looked at a window of nodes created between
each ProcessStmt.  This optimization can be reclaimed my merely expanding the window to N number of nodes.

By changing all of the throw() specs to noexcept I've been able to compile and link all of the source files into a dylib.  Prior to this substitution the changed functions were calling __cxa_call_unexpected which isn't implemented yet.  However in none of these cases do we actaully want __cxa_call_unexpected to be called.  Primative buildit script added.

A REG_SEQUENCE instruction is lowered into a sequence of partial defs:

  %vreg7:ssub_0<def,undef> = COPY %vreg20:ssub_0
  %vreg7:ssub_1<def> = COPY %vreg2
  %vreg7:ssub_2<def> = COPY %vreg2
  %vreg7:ssub_3<def> = COPY %vreg2

The first def needs an <undef> flag to indicate it is the beginning of
the live range, while the other defs are read-modify-write.  Previously,
we depended on LiveIntervalAnalysis to notice and fix the missing
<def,undef>, but that solution was never robust, it was causing problems
with ProcessImplicitDefs and the lowering of chained REG_SEQUENCE
instructions.

This fixes PR11841.

When not using subsections via symbols, the assembler can resolve
symbol differences (including pcrel references) to non-local
labels at assembly time, not just those in the same atom.
